Life is like a box of cereal. You always know what you're gonna get. Unless it's a cockroach. Then you'll be unpleasantly surprised.
This one time a cockroach came into my room at night and I thought it was my cat scratching at the door because it was making this weird scratching noise. Anyway, I get up and open the door and no cat is there. Then I turn around to get into my bed kinda scared (I am a wimp) and I step on it... with my bare foot. It was rather disgusting.
