Owen (out of nowhere) in a perfectly normal voice: I have to clean up my room.
Me: Okay.
Owen, in an 80% snotty tone: I guess I have like three seconds to do it. Hmph.
Me: ?????
Owen: I guess I hvae to go do it right now.
Me: If you want to.
Then he stomped off upstairs.
What?! When did he turn into a teenager?
