We've never read Eudora Welty here, so we're going to discuss her best-known work, the Pulitzer Prize-winning "The Optimist's Daughter." This short novel, which began as a story in the New Yorker, is about a woman who travels to New Orleans to take care of her father after surgery. I've been meaning to read Welty for years, so I'm happy we're doing this now.

Bring a friend, bring family, and bring that neighbor that you kinda know... Come one, come all for some free table tennis. Note: Because we have been playing regularly for years, members tend not to RSVP. If there are any questions, feel free to message.

PLEASE NOTE: BAD stands for Broadway And Disney. Mostly Broadway and Disney, all night. That's right. No karaoke mic, just an old fashioned singalong. Celebrate Women’s History Month the BAD Singalong way: loud, dramatic, and powered by women and femmes who knew exactly what they were doing. This singalong centers divas, villains, leading ladies, and complicated icons whose songs still demand to be sung at full volume. The playlist is shaped by the people who show up and speak up: a crowd-built mix of Broadway and beyond, big feelings and bigger belts, petty anthems, power ballads, and unforgettable key changes. If it’s a song that lives rent-free in your head, there’s a good chance it'll make the cut. No solos required, enthusiasm strongly encouraged. Come scream-sing with friends, meet new ones, and honor Women’s History Month together, loudly, and on purpose. 💅🎤 I'll get there by 6:30 pm to setup. Doors open by 7 pm, if you get there early. We'll be upstairs. You can join our FB group here to keep up with news and events, as well as vote for songs in the playlist: fb.com/groups/BADSingalong Generally looking at third Thursdays throughout 2026, adjusting for scheduling depending on conflicts for hosts, and holidays for regular attendees, which will be confirmed no later than the month before.

Let's play monopoly in the open area called "The Landing" at the Crystal City Shops. The Landing is right at the Crystal City metro stop and, if you're driving, there is free parking [on weekdays after 4pm and weekends] in the garage. See below for more details. With many tables for games and nearby eateries in the mall, it is a fantastic location for playing board games. We'll be starting at 3:00 pm, but feel free to wander in whenever you'd like.Please RSVP to play. If you'd like to start earlier, feel free to mention that in the comment section. If everyone is already in the middle of games when you arrive, please don't hesitate to pull up a chair and watch a game in progress. We will play a minimum of 3 and a maximum of 6 people at each table. This is a friendly group of competitive and non competitive players and our different backgrounds and different experiences of Monopoly make for interesting conversation during the games. If you're taking the metro, exit at Crystal City and you can walk to The Landing without having to go outside. When you come up the first set of escalators, turn right to enter the underground shops and then turn right at Rite Aide. Continue straight and The Landing will be the large open seating area on your right, next to San Antonio Bar & Grill and Subway. If you're driving, parking is free in the garage. Enter the garage for 1750 Crystal Drive on 18th Street and take a ticket. (You'll need this to exit, but there's no charge). Take the elevators up to Level S. The Landing is the large open seating area next to San Antonio Bar & Grill and Subway. If that parking garage is full, exit the garage and turn left on 18th and left again on Crystal Drive. A second parking garage is located on Crystal Drive between 18th Street and 15th Street. This is a link to a map of the Crystal City Shops: http://www.thecrystalcityshops.com/ The Landing is in the yellow section on the map near the San Antonio Bar & Grill and Subway.

The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA
