A very Midwest way to spend the night. Euchre Night at TownHall Short North brings cards, cocktails, and community together for an easygoing evening of friendly competition. All skill levels welcome—confidence encouraged.

This is a free, in person meeting. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.

This is a free in-person meeting. Let's talk about relationships in such a way that you can really benefit from the knowledge. We can talk about * Soulmates * How to start a relationship * How to maintain a relationship * How to pick the right partner * How to recognize the red flags * How to improve communication * How to avoid argument and fights * How to increase trust You ask the questions, we'll talk about them. 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 sponsored the Dianetics & Scientology Self-Improvement Center.

**⚔️ Introduction to Wargaming & Painting Miniature Soldiers at The Arcane Foundry ⚔️** Join me in **The War Room at [The Arcane Foundry](https://share.google/S5i6DYJnJteHWeKtd)** for a laid-back evening of hobby talk and tabletop fun! For just **$15**, you’ll get a **3D-printed regiment of 20 high quality resin models** of your choice to paint — a **$40 value!** Bring your creativity, relax, and let’s make something awesome together. **Choose one from Below:** * 20 Orc Warriors * 20 Empire Soldiers * 20 Dwarf Warriors * 20 Elf Spearmen Step into a world where strategy meets artistry — and where every painted figure tells a story of battle, honor, and imagination. Join **Daclaud** at **The Arcane Foundry** for an evening that introduces newcomers and enthusiasts alike to the timeless craft of **tabletop wargaming** and **miniature painting**. My own journey began with a fascination for fantasy — knights in armor, grim and hardened warriors, and monstrous creatures locked in epic battle. That passion led me to **Dungeons & Dragons**, where I painted my first **Basic Heroes set** and felt the spark that comes from bringing a character to life in miniature form. Not long after, I discovered **Warhammer Fantasy** and **Warhammer 40,000**, and I was hooked. The vision of vast armies clashing across the table — each unit meticulously painted, each story unfolding through dice and imagination — became my creative obsession. During this event, we’ll explore the **origins of wargaming**, from its early military simulations to the richly detailed worlds of modern tabletop battle systems. You’ll learn how to **build and customize your own armies**, paint your first figures, and experience the joy of turning strategy and storytelling into a hands-on art form. Whether you’re drawn by the lore, the hobby, or the thrill of commanding miniature legions, this introduction will open the gates to a world that has captivated hobbyists for generations. ** RSVP today and join us at The Arcane Foundry — where every brushstroke and battle tells a story.**

**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** *Spec-Driven Development with GitHub Spec-Kit: From Intent to Implementation* Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA

Join us for something different as we get together to see EPIC: ELVIS PRESLEY IN CONCERT! While researching his 2022 film, director Bas Luhrmann came across and compiled rare and previously unseen interviews and videos of Elvis in concert to create “one of the most exciting concert films you’ve ever seen!” Here are details, a trailer and our plan for this event: DESCRIPTION: Part documentary, part concert film, the latest from director Bas Luhrmann is a follow-up to his 2022 film starring Austin Butler. While researching the film, he came across 68 boxes of previously unseen interviews, concert performances and outtakes from previous films. A combination of offstage and onstage Elvis, comes a film that “befits the magnitude of Elvis as a performer but also offers deeper revelations of his humanity and inner life." It is written/directed by Baz Luhrmann (ELVIS, MOULIN ROUGE, THE GREAT GATSBY) and stars the legendary Elvis Presley! TRAILER: https://www.youtube.com/watch?v=NmqWusmzp0k BUZZ AND ACCLAIM: The film screened at the 2025 Toronto Film Festival where it was the runner up in the category People’s Choice Award for Documentaries. Next Best Picture says, “Certain to energize longtime fans and generate new ones for generations to come, EPiC: Elvis Presley in Concert is a masterwork of montage.” And according to the NY Post, whether you have a room in the house devoted to Elvis or not, this truly “Epic” concert film is an energizing experience!” PLAN: We’ll plan for a pre-show bite at nearby BRAVO around 5 or 5:30pm followed by a 7pm-ish showing on one of their larger screens. Once showtime is announced, advance ticket purchase is advised. Please list your seat number in the Comments below.
