Me: B, you get a pink star for being a good listener today. And another star for being helpful.
B: Yes, but sometimes I pick my nose a little bit.
Me: I don't have space on the sticker chart for that.
B: There are whales underwater, and sometimes they blow their nose. But not in our pool. I tell them they can't pee in our pool. I only pee in the ocean now.
Me: Ok, you can have a star for that.
