Brussels Singles Relational Lab — Facilitated Connection Experience
# Tired of dating apps culture and surface-level?
This is different. And people often leave surprised by how quickly strangers can feel human, warm, honest, and real again.
Free to RSVP,
👉 $59 to confirm your spot
[https://consciousconnectionsclub.com/stayconnected](https://consciousconnectionsclub.com/join)
Relational Labs is a guided connection experience for singles who want more honest, playful, emotionally intelligent interaction — without performance, pressure, or endless small talk.
This is not speed dating.
Not networking.
Not “pitch yourself to strangers.”
It’s a facilitated relational container rooted in psychology, emotional intelligence, attachment work, social dynamics, nervous system awareness, and real-world human connection — made practical enough that you can actually live it instead of reading another 50 books about it.
## What happens
• A 2-hour guided online relational experience
• Real-time connection exercises designed to create authentic interaction
• A format that adapts in real time to whoever is present
• Optional participant-led in-person continuation afterward
• WhatsApp connection thread after the session
## This may be for you if:
• You’re tired of shallow or repetitive social spaces
• You want deeper connection without forced intimacy
• You enjoy personal growth, psychology, communication, or relational work
• You’re open to meeting people in a more intentional way
## Important
This experience runs with whoever is present and takes its own shape each time.
Sometimes expansive.
Sometimes intimate.
Both are the real thing.

**A MESSAGE FOR NEWCOMERS:**
*In the three years of hosting this coffee group, I have met many people who struggle with anxieties when coming to an event for the first time. Sometimes, it took them more than one attempt before being able to join.*
*Occasionally, people reach out to me before the event, and I have always been grateful for that as it offers the opportunity to communicate with each other and to find the best and most gentle way for that person to join the group.*
*I would like to encourage everyone who struggles with this to contact me before. It would really be too bad if you can't join us, as it mostly gets better the second or third time you come.*
*In addition to that, if you arrive and notice any signs of nervousness or fear, you can always let me know right then.*
**THANK YOU AND SEE YOU ALL ON SATURDAY!**

Silent Walk in the Forêt de Soignes
We will be walking through the forest for a little over 1 1/2 hours, silently, just noticing the world around us and inside us. The idea is to experience the magic of a different type of walking, The invitation is to slow down and notice what is going on inside you and around you.
Very often people experience a closer connection with nature and with self, with sometimes surprising insights.
*Please make sure you are fit enough to go the 4.5 km distance. We will be walking slowly, but we will not take any breaks.*
We will be meeting at the Hermann Debroux Metro at **14h**. (Exit straight ahead after leaving the platform--on the Loxam side).
If you RSVP as coming, please be on time. We will be starting our walk from there 5 min. after the hour sharp.
There is the renovated Maison de Prieur at the exit of the forest where we could gather for a drink or a meal after our walk, depending on what you feel like.
Looking forward to an inward adventure? Come and join us on **Saturday, July 4, at 14h**
My phone number is 0472 92 11 76, in case you need to communicate with me.

🇧🇪🇪🇸🇮🇹 Language Picnic & Games 🌎🌳🧺🏸 🎲 (TBC🌤️)
What's up Friends! 👋
If the weather gods feel generous 🌤️, we’re going full park mode: picnic 🧺🌳, games, laughs… and a touch of chaos ✨
‼️If not - we'll switch to the usual indoor format at Le Pantin or Café Leopold PDN.
📍Where
Park Cinquantenaire, Tour de Tournai 🏰 (that little castle-looking thingy in the park). Look it up on Google maps! We'll also post some pics of the exact spot. Can’t find us? 🤷♀️ Just ping me here.
💡 The Idea
Chill picnic with multiple language and game groups: Spanish, French - for sure, Dutch, Italian - if there is interest, other languages - TBD. Join a group and speak ONLY that language! Full immersion, baby! 🔥
Bring your own drinks 🧃, snacks 🥪🍓, blanket, and games 🎲🏸 (sharing always appreciated 😋).
We’ll break into small groups depending on the vibe: languages, games, other chats, sports.
⏱️ Timing
We kick off at 14:00 under the thickest shade we find. Stay as long as you like. Some of us would likely stay until the sun sets.
Joining later? Just drop a message in the chat in case we decide to move 😊.
🎲🏸 Games
All games are welcome in the park - boards, cards, balls, random stuff! I’ll have a few with me, but feel free to add your own favorites too.
🚦On the waitlist but really want to join? Or got any questions? Just DM me.
📢 Extra info might drop in the group chat or via DM 💬. Check your messages 👀 the day before so you don't miss anything critical 🙄.
🐈⬛ The Friends Code:
👉 Games we play = group decision
👉 Linguistic chats = full immersion in one language. No one cares about mistakes. Just speak!
👉 Smaller groups = cozier vibes
👉 Got a favorite game? Suggest it or show up with it
👉 Can't make it? Cancel on time so someone on the waitlist can grab your spot
👉 If you’re on the waitlist, showing up is at your own risk 😄
See you there, folks 😉
Sunday Electronics Workshop
This workshop series is a **follow-up to the ESP32 Robotics workshop**, but with a different concept. Here, there will be no subject set in advance, instead **all participants are welcome to join at any point and at any level, from beginner to expert**. Beginners will be guided though the basics (C programming, how to use measurement tools, soldering, PCB design, etc…) and can get advice on what tools and kits to start with, others can come with their own projects to get help or share some knowledge.
## Requirements
* Bring your own laptop (Windows, Linux or Mac)
* Any microcontroller/dev kit to develop your project(s). If you are a beginner and don’t know what to buy, come and we’ll find the best starter kit for you !
* A strong desire to learn stuff, good mood and some patience !
Caffe Leopold Porte de Namur: Sunday Coffee & Friendly Conversations ☕😊
**Join us for a relaxed Sunday morning meetup at Caffè Leopold in Porte de Namur!**
We’ll meet from 11:30 to 13:30 to enjoy coffee, brunch, and easy conversations in a friendly atmosphere.
It’s a great opportunity to meet new people, practice English or French, and spend a nice Sunday morning together.
Everyone is welcome — whether you come alone or with a friend. Just bring your good mood and be open to meeting others 😊
After the meetup, for those who want, we can also continue with lunch in a nearby place 🍽️
**📍 Location: Caffè Leopold, Porte de Namur**

Columbus Code & Coffee 88 @ Improving
Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you!
**What to Expect at the Intro Circle**
\~\~\~\~\~\~\~\~\~\~\~\~\~
Near the beginning of the event (1:30 pm), we do a standup:
* Organizer announcements, updates, and logistics
Round 1 - (7 secs max):
* Your name
* What you're working on
* What you can help others with
Round 2:
* Community events you wanna plug. If none, that's cool too.
Round 3:
* Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool.
After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!
Stop Guessing: How to Measure and Improve LLM Outputs
Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on.
That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable.
In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork.
This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it.
We’ll cover:
* Why “it looks good” is not enough
* How to improve prompts by changing the input, context, and constraints
* How to compare LLM outputs more systematically
* Basic evaluation techniques for accuracy, consistency, and usefulness
* How embeddings, cosine similarity, and scoring can help evaluate results
* Where automated evaluation works — and where humans still need to stay in the loop
By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve.
LOGISTICS AND PARKING:
The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks!
The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
How to Take Control of YOUR Mental Health
It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind.
Find out what the reactive mind is, and in the process find yourself.
Here is the secret of being positive and free:
Thinking positively is not enough.
You also have to get rid of the negative thinking.
Your mind is like a garden.
You can plant many beautiful flowers in it, but if you don't get rid of the weeds when you plant your flowers, the weeds will soon take over the whole garden.
A positive thought is like a flower in your mental garden, and a negative thought is like a weed.
You cannot expect to have a positive mindset if you continue to have negative thoughts dwelling and growing there.
So, how do you get rid of the negative thoughts? That's what this Meetup is all about. Attend this local meeting and find out!
The Meetup event will be led by a consultant who had helped many people live happier in life.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.
This group is created by the Dianetics & Scientology life improvement center.
The Non-competitive Tennis Partner Program
We connect you with up to 30 Men or Women tennis partners close to your PLAYING REGION and skill level.

Players will meet up to play a tennis match or just to hit around. Just go through the [Join Page](https://www.tenniscolumbus.com/partner-program) to enter this program.

IxDA Chat n Pancakes
You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday.
But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to.
Thanks to the team at Nationwide of supporting the group.
