We all sing. In the car, in the shower, at the pub. But many of us are unsure about our ability to sing in front of other people. The Arlingtones Barbershop Chorus wants to help you get the most beautiful sound possible from your voice with the confidence to perform. We love to sing – that’s why we do it and have for over 60 years. Join us for a Tuesday evening and we'll show you what Barbershop Music is all about. No experience or materials necessary.

You are only successful as your ability to communicate. Most communication problems don’t come from saying the wrong thing. They come from moments when understanding quietly disappears— and no one knows how to bring it back. This live, in-person workshop is for people who want communication to feel **easier, calmer, and more effective** in real situations—not just in theory. **It talks about completely different techniques than previous events given here.** ### **You’ll likely relate if:** * You replay conversations later and think, *“That’s not what I meant.”* * You hesitate or overthink when it’s time to speak up. * Conversations drift into tension even when everyone has good intentions. * You want to connect better—but don’t want scripts or fake confidence. If any of that sounds familiar, this session will feel immediately relevant.This is **not a lecture** and not a networking event. It’s a **guided, interactive workshop** where you’ll: * Learn why conversations break down in the first place * Experience what actually restores understanding * Practice being more present and composed in real time * Leave feeling more comfortable in conversations—without forcing anything Most people notice a difference **during the session itself**, not weeks later. Workshops like this are rare because they: * Give you something immediately to apply and do * Focus on fundamentals instead of trends * Require live participation to be effective If communication has ever felt like a bottleneck in your life— skipping this tends to feel obvious *after* the fact. ### **Who this is especially good for** * Thoughtful, introspective, or introverted people * Professionals who want clearer communication at work * Anyone navigating relationships, boundaries, or confidence * People tired of tips that don’t translate into real life You don’t need to be outgoing. You don’t need experience. You just need curiosity.

Everyone’s prompting. Few people are judging. This talk shows how a playwright uses multiple LLMs and vibe coding to build a custom evaluation loop: a digital dramaturg that checks scenes against an outline like a living spec. If you design, build, or eval AI systems, you’ll leave with a new mental model for using LLMs as QA, not just content engines. **Featured speaker:** * [Soo-Jin Lee](https://www.linkedin.com/in/soo-jinlee/)\, Gen AI Conversation Designer \| Prompt Engineer \| LLM\, NLU\, NLP \| Human in the Loop \| Former Teacher \| Playwright **Location:** AWS Skills Center, 1550-G Crystal Dr, Arlington, VA 22202 **Drinks and Networking After:** --> Alamo Drafthouse, 1660 Crystal Dr, Arlington, VA 22202 (2nd Floor) **Description:** Join us at AI Innovators Network for our upcoming meetup in the Mosaic, which is dedicated to exploring the latest trends in Artificial Intelligence.

Join members of the local UX and Digital Design community for a casual monthly breakfast. There _might_ be a little snow, but there _will_ be effectively infinite serve-yourself coffee, so it evens out if you ask me. Just a reminder, while the other locations are great too, we’re at the Lane Ave one this time.

In this local meeting, you will discover knowledge that you can use to get over the past. The key to improving your personal motivation, self-confidence, and happiness is to get over your painful memories. When you become free of your past, you will be free from stress, anger, anxiety and depression. Studies show that negative emotions can affect your health. By being free of negative emotions, believe it or not, you will most likely even look younger, feel more energetic, and become healthier! 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 brought to you by the Dianetics and Scientology life improvement center.
