Overheard

There's an English Literature exam this morning, and there's a queue of kids outside my prep room waiting to get into the computer suite next door.

Girl 1: I can't believe I was called stupid right before my exam.
Girl 2: What happened?
Girl 1: (boy) said I was as thick as 2 short planks.
Girl 2 (happily): Oh, that's a simile!
