Chess

Van recently learned how to play chess, here is he teaching Esther.

Van: "Mom, it's called 'Chest'"
Me: "No, it's called Chess'
Van: "No it's CHEST. I like calling it Chest."
Me: "Van, you can call it whatever you want, but it's actually called 'Chess'"
Van: "Well I'm going to teach my kids to call it Chest."
Me: "You are welcome to do that."
