Matt's "Worse Day Ever!"

After picking up Matt from school one day in February he says:
Matt: I had the worst day ever.
Me: Why?
Matt: I think I have a girlfriend.

They had a "post office" set up in school during the month and the kids are encouraged to write letters to each other. Evidently a girl in the class put 2 hearts by her name on the card she gave to Matt. Which obviously means that she wants to be his girlfriend.
