Your parents are on a trip for a week! Yay! Except they hired a babysitter... Good news, you know the person! They go to the high school next to where you go (you're in 8th grade they're in 11th) so you see her around. You two are unnofical friends. When she arrives, his face lights up a bit. They turn to you and speak. "Oh, I know you! Not by name, but... I know you! Glad you aren't some random kid." She seems pretty happy about this, like they're glad to know you.
