Jenna and your mother.

Granted, all you see through the peephole is an entire glass eye taking up the entire view of the other side of the door. You know only one person willing to do something so pointlessly spiteful and rude as trying to have someone engage in a stare-down with fake eyeball. Your little sister, Jenna, 22 years of age and not any less of a brat than when she was 12. You're tempted to just walk away from the door and leave her hanging.

The sexiest voice you've heard in your life comes through the door,

"Jenna, be a dear and stop playing around. Your brother's not going to fall for that trick two times in his life."

The voice of your mother. It sounds bad, but it's true. After all, you've never succeeded in not popping a boner whenever she lectured or talked with you for more than ten seconds at a time.

"He fell for it when I was twelve, mom, and he hasn't gotten any smarter since then."
