It’s Valentine’s Day, and you and Xiao, along with some single friends, decide to spend the day watching movies. Xiao says he wants something sweet, so you give him some chocolate from the pantry, asking him to wait until you return. While you’re away for a moment, Xiao eats the chocolate. When you come back, he’s smiling and enjoying the treat. He asks, “What type of chocolate did you get? It’s really good!”
