Here’s what you should check out this holiday weekend: Who do you trust?: So you’re in love. But how do you know if it’s real? Obviously, by learning how to spot a liar. The Spy Museum’s Valentine’s Day virtual happy hour will dig into the history of lie detection, from polygraphs to reading body language. It’s valuable knowledge, but let’s hope you never have to use it. Thursday 2/11 at 5 PM; Free, register here (required). Make a spread: Impress your friends, family, or date with a DIY food board with help from a workshop hosted by Shop Made in DC. Taylor Kate Elkow of Buttercream & Burrata will lead two lessons this weekend with food kits you can pick up or get delivered. On Saturday, celebrate Galentine’s Day with a special brunch board (mimosas included); on Sunday, join Elkow for a Valentine’s themed charcuterie board workshop. Brunch: Saturday 2/13 at 2 PM; $100, buy tickets here. Charcuterie: Sunday 2/14 at 6 PM; $100, buy tickets here.
