The cast: Mom, Girl #1 (6 years old), Girl #2 (9 years old), and Girl #3 (5 years old. Doesn't really figure into the story. Spends the entire scene sucking her thumb.)
Backstory: It's been a long, grumpy day for everyone. Lots of whining, shrieking, complaining, and yelling. The kids haven't been all that great either.
Mom looks in her rearview mirror and sees surly Girl #1 slumping down in her booster seat, definitely not taking advantage of the safety benefits of said booster.
Mom: "Girl #1! Sit up straight!"
Girl #1: "No! I don't want to! Why should I?"
Mom: "Because it's not safe to sit like that."
Girl #2: "Yeah, you might get hurt if mom smashes into the car in front of us."
Mom: "Sit up!"
Mom sighs deeply and lets her mind wander to a distant, tropical island and a cabana boy or two. Or three.
Girl #1: "ARGH! I don't want to! I don't want anyone to see me! I don't want anyone to know I'm part of this crazy family!"
Girl #2: "Don't say that."
Girl #1: "I don't want anyone to see me in this crazy car with this crazy family!"
Girl #2: "Girl #1, no one can tell we are crazy just by looking into our car."
Mom can't decide whether to laugh or cry.
