At lunch the other day-
Me: Olivia, take your feet off the table.  (For the twelfth time)
O: Why?
Me: Because they have germs on them and I don't want them on the table. Also, because I'm the mom and you're the little girl. Your job is to obey me.
O: Why?
Me: Because God said. He said, "Kids, obey your parents."
O: I didn't hear him say that.
