In the process of moving our bedroom from one room to another, my husband left our queen-sized mattress propped against a wall. When he came back into the room, the mattress was laying on the floor, with Rosie suspiciously nearby. The ensuing dialog went something like this:
Dad: Rosie, how did this mattress get on the floor?
Rosie: Um, I dunno.
D: Did you knock it over?
R: Unh-uh. It fell over all by itself!
D: And where were you when it fell over?
R: I was jumping on it!!
