I was walking through our house when I saw Jake. He was watching me stone-faced with eyes open wide and bugged out. In our house, that means one thing — staring contest. I returned the stare as I walked nearer and bent closer to his level.

Closer.

Closer.

Until he reached up and poked me in the eyeball and yelled, “you blinked! I win!”

Yeah, he got me: I definitely blinked. I think I can still see his fingerprint on my cornea.
