The Great Crumb Caper of '12

While cleaning out Schatz's room...

Me: Schatz, you can't eat food in your room.

Schatz:  Why?

Me:  See this (pointing to a beetle)?  When you eat food in your room, the crumbs draw bugs.

Schatz:  Those are NOT my crumbs!

Me: Schatz, please.  No food in your room.  Do you want bugs? 

Schatz (indignantly):  Those are NOT my crumbs. Those are Maura's.

Me: Oh, yeah?  Maura brought the crumbs into your room.

Schatz: Yes. Maura is bringing HER crumbs into my ROOM!
