Slow dating - Connection Games [Affinitee Utrecht, April Edition]
Slow dating - Connection Games [Affinitee Utrecht, April Edition]
## Love is in the air…! After the crazy success of our first event, we're back with more connection games! This time, the games will be much shorter (15-20 mins each) to allow for easier rotation. For those who're new here, Affinitee hosts slow dating events focused on discovering relationships built on compatibility over superficiality! **No more swiping, skip the bad dates!** ### *This is how it works:* 1\. Before you arrive at the meetup\, you fill in a fun 5\-10 minute questionnaire before registration below \(if you haven't already\)\. We explore different aspects of relationship compatibility using this questionnaire\. To make use of the pre-matching facility, we recommend registering on the website as well. You may sign up here [https://affinitee.eu/au-event-3](https://affinitee.eu/au-event-3) 2\. A match will be automatically assigned \(if available\)\, based on your given criteria \(age range\, children\, location etc\.\) as well as the overall compatibility score based on your questionnaire answers\. 3\. At the event\, you will be able to try out a multitude of board/card games that are specifically chosen to explore various aspects of relationship compatibility \(moral values\, decision making etc\.\)\. 4\. After each game\, you can choose to switch partners\, or continue with the same person\, based on input from either parties\. 5\. At the end of the event\, IF you did indeed feel a spark with someone at the event \(and it is reciprocated\)\, we help you arrange a date with them\. You do not even have to exchange contacts\! **[!!IMPORTANT!!]** We recommend signing up through our website to guarantee a match as early as possible. But of course, even if no match isassigned to you due to late registration or gender imbalance, a majority of the games are still played as groups! *So nobody gets left out and everyone has a chance to meet and match with other singles.* We believe in conscious, compatibility based matchmaking. Don't waste your time dating the wrong people!
Create. Express. Unwind - Art & Self-Expression for Women — No Experience Needed
Create. Express. Unwind - Art & Self-Expression for Women — No Experience Needed
This is a facilitated creative session — not a class. You'll receive a starting prompt, access to paint, collage materials, texture, and colour, then two and a half hours to follow whatever feels right. No instruction. No judgement. No wrong moves. I designed this for women who spend their days in logic, deadlines, or high performance — and who have quietly stopped making things just for the joy of it. This session is permission to start again. We work in a small, intentional group. Music plays. Tea is ready. What you make is entirely yours. ### ✅ What's Included * All creative materials (paint, canvas cards, collage, pastels, mixed media) * A starting prompt to spark your session * Curated ambient music and calm space * Tea, coffee, and light bites * Your finished work to take home * Optional group sharing at the end. *** ### 🎒 What to Bring * Yourself and an open mind * Comfortable clothes you don't mind getting paint on * Nothing else — everything is provided ### 📋 Activity Itinerary | Step | Title | What happens | | ---- | ----- | ------------ | | 1 | Welcome & settle in | Tea, introductions, no pressure | | 2 | Meet your materials | Explore what's on the table | | 3 | Receive your prompt | One sentence to start from serving as a gateway to the experience | | 4 | Make freely | 60 min of creative flow time | | 5 | Reflect & share | Optional — share or just explore what others created | | 6 | Wrap up | Take your work, leave lighter |
IN-PERSON Book Club Meeting - KAFKA ON THE SHORE by Haruki Murakami
IN-PERSON Book Club Meeting - KAFKA ON THE SHORE by Haruki Murakami
'KAFKA ON THE SHORE' by Haruki Murakami 'The aging Nakata, tracker of lost cats, who never recovered from a bizarre childhood affliction, finds his pleasantly simplified life suddenly turned upside down. There is a savage killing, but the identity of both victim and killer is a riddle. Kafka on the Shore follows the fortunes of two remarkable characters. Kafka Tamura runs away from home at fifteen, under the shadow of his father's dark prophesy. The aging Nakata, tracker of lost cats, who never recovered from a bizarre childhood affliction, finds his pleasantly simplified life suddenly turned upside down. Their parallel odysseys are enriched throughout by vivid accomplices and mesmerising dramas. Cats converse with people; fish tumble from the sky; a ghostlike pimp deploys a Hegel-spouting girl of the night; a forest harbours soldiers apparently un-aged since WWII. There is a savage killing, but the identity of both victim and killer is a riddle. Murakami's new novel is at once a classic tale of quest, but it is also a bold exploration of mythic and contemporary taboos, of patricide, of mother-love, of sister-love. Above all it is an entertainment of a very high order.' ***Please read the book and join us for a lively discussion (in English) about the contents during our afternoon book club meeting.*** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **PLEASE NOTE:** This is an IN-PERSON event in Amersfoort, The Netherlands.

The story we tell ourselves: Self-Image vs Self-Esteem
The story we tell ourselves: Self-Image vs Self-Esteem
Have you ever noticed how the way you see yourself can change depending on the situation? One moment you feel confident and capable — the next you start doubting yourself after a small mistake or comparison. How do you see yourself on LinkedIn or social media — is it that persona or the quiet inner picture you carry, about who you are? Sometimes that picture feels strong and confident. Other times it becomes surprisingly fragile after criticism, comparison, or a simple mistake. In this meetup we’ll explore two closely related ideas that shape how we experience life: **Self-image** — the picture we hold of who we are **Self-esteem** — how we feel about that picture Through conversation and simple reflection exercises, we’ll look at questions like: * Where does our self-image actually come from? * Why can our confidence rise and fall so quickly? * What role do comparison, expectations, and inner criticism play? * And how can we build a healthier relationship with ourselves? Expect an open and thoughtful discussion — not a lecture. You’re welcome to share your thoughts and experiences, but there’s never any pressure. Listening is just as valuable. If you're curious about how our inner narratives shape our lives, come join the conversation. **Who is this for?** Anyone interested in personal growth, psychology, and understanding how our inner narratives influence our lives. **What to expect** * Guided discussion prompts * Reflection exercises * Practical insights you can apply in everyday life **Tone** Supportive, curious, and judgment-free. **Disclaimer** This is not therapy — It's a thoughtful conversation about being human.

So come and join us and meet other local atheists, along with agnostics, heathens, humanists, skeptics, and anyone else who's 'hell bound'!

What If Your AI Could Be a Team? - Chad Green
**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
