Ed: Mike, where the hell are you?
Mike: I am still at school.
Ed: Shouldn't you be home already?
Ed: I don't have the key.
Mike: I've got a chess club on Tuesdays.
Mike: For the past three years.
Ed: Could you skip it just once?
Mike: Not when I am winning. You want the key, you come down here.
Ed: All right chess master. Be there in an hour.
Ed couldn't get in because he didn't have the key, and Mike was at his chess club meeting. Ed had to go get the key from Mike.
