The Neighborhood Watch

Thalia wanders over to the neighbor's house, stands in front of their porch window, and watches TV for a bit while I'm unpacking the car.

Me: Thalia, don't stand in front of their window!...
Laura: Where's Thalia?
Me: She's being a peeping, uh...what's the feminine for Tom?
Laura: Thalia.
Me: Haha!
