Adventures in Babysitting

Older nephew: I have to go find mommy and daddy.
Me: Mommy and daddy went out, but they'll be back.
Older nephew: But they might get lost.
Me: Mommy and daddy won't get lost. They'll be back later.
Older nephew: But it's dark.
Me: It's okay. The car has lights, so they can see in the dark. So they won't get lost.
Older nephew: Oh! (Big smile) Okay!
