Clever insight

We overslept this morning. Running very late actually. Holly was a little worried in the car going to school, she doesn't like being late.
- Don't worry about it, says Richard. It's not your fault that you're late, it's mine and mummy's, it's our responsibility to make sure you get to school.
- Yeah, OK, she says. If it was my responsibility, I probably wouldn't go to school at all.
