so maybe he has a little leverage

I walk into the computer room, where my brother is sitting reading something online.

Me: "So what are you reading?"

Brother: (after a mad scramble to change windows) "Nothing! Nothing!! Go away!"

(too late)

Me: "Oh, Harry Potter fan fiction? So what? Sometimes I read Harry Potter fan fiction."

Brother: "Well I don't!"

Me: "You were clearly just reading it."

Brother: "I was not!!"

Me: "Wait till I tell all your friends."

Brother: "Wait till I light all your yarn on fire!"
