Mummy and I go to school to collect 10YOS and 8YOD (we had parent-teacher meetings that afternoon).
10YOS walks up to us waving a permission slip for the Year 5/6 school camp, to be held at a Department of Education facility about half an hour out of town.
10YOS (triumphantly): At last, we can have an overnight camp.
Mummy (with a straight face): Oh, honey, didn't you know, you can't go on that camp!
10YOS (matter-of-factly): Yeah, that's okay, I didn't want to go anyway.
Mummy (baffled): You mean, you're thrilled you can go, but you don't want to?
10YOS: No, I'm not interested.
Mummy: You're weird.
