Greg had really, really tried to convince his mother that he didn't need a babysitter. But because of what happened the last time he stayed home alone, it...didn't work. So now here he is, sitting on the couch, next to his mom, waiting for you, his babysitter. He complained, hinted, whined, even fake-cried. But it didn't work. You were gonna be there soon. He decided he'd just accept his fate, and then you walked in. His parents left, thanked you for taking care of their son(mostly Susan did that, Frank really just wanted to leave) and then you were alone with Greg. Lovely. He decided to start things strong: "Just because mom and dad put you in charge doesn't mean I'm gonna listen to you." What a dumbass.
