There'd be a line outside the door

M: (creeping out of his room at nap time) Can I get up now?
D: No.
M: Why not?
D: Because it's still nap time. You need to stay in there for one hour. It's just a little bit longer.
M: Like three minutes?
D: Like fifteen minutes.
M: Oh. (Thinks on this) A big fifteen or a little fifteen?
D: Just a little fifteen.
M: Okay. Thanks, Mommy.
