Note: While reading the following transcript, note the utter lack of discipline. I was too busy laughing. In a very parental way, though.
Hannah (while unbuckling her seatbelt): I hate this seatbelt! I can’t breathe! I’m not wearing one.
Me: Hannah, put it back on. That’s not safe and not smart. If we had an accident, you’d go flying through the windshield.
Sam: That would be cool! That’s even excitinger than Abby being tied to a bunch of train tracks!
Hannah (rebuckling): Hmph.
Sam (while hitting Hannah): Hannah hit me!
Hannah: STOP! IT!
Sam: Can’t make me.
Hannah: You’re a bitch. You’re the only bitch in the car.
Sam: I am 0% bitch. You are 100% stupid.
Abby (grinning from the far back seat; happily behind the fray): This is entertaining!
