I was recently playing Lego with my son. He had separated the Star Wars & the Indiana Jones figures & we were locked in epic battle. He kept changing the "rules" though, so that I could never win. I finally told him I didn't like that, and said that if that's how he played with his friends they probably wouldn't like it either. He assured me, "Don't worry Mom. I always play like this. My friends are used to it."
