Lady, seeing long line for toilet: What a long line! Is there anyone in the men's room? I'll use it, why not? It's the same! (Knocks on door, gets no answer. Opens door)

(stands there for 30 seconds with grimace, complaining)
Poor little boy, coming out of bathroom, in shaky voice: There's… There's no one else in there.
