5yo (lying on the floor outside the locked bathroom door): Hey! What are you doing in there?
8yo: I'm going to the bathroom!
5yo: Oh. Which one?
8yo: None of your business!
5yo: Are you reading a magazine in there?
5yo: Are you sure?
5yo: Well, but I can hear the pages turning...
5yo: Hey! My hand can fit under the door! See?
8yo: Go away!
5yo: You're not s'posed to say 'go away' to me.
8yo: And YOU'RE not s'posed to bother people in the bathroom!
5yo: I'm not bothering you! I'm just letting you see my hand under the door! I'm moving my fingers, can you see them? See, they're wiggling! I'm waving at you! Are you waving back?
