I kept my best poker face as Harry came out of his room and stumbled toward the icebox. He opened it and rummaged around for a Coke.

A lesser man would have twitched or tensed in anticipation, but I didn't move. I was careful to keep my eyes half-shut in feigned sleep.

He brought the can up, popped the tab-

and a geyser of soda erupted in his hands, spraying everything within a three-foot radius. Mostly his face.

He yelled in surprise, and fell back onto the floor.

I let out a quiet chuckle.

Payback, little brother.
