We were sitting eating dinner today and talking about our days. The kid mentioned that she's forgotten her taekwondo uniform on Monday so she had to wear just her belt. This led to my husband teasing her about going to class wearing no clothes. She rebutted that that concept was "disgusting. But way more disgusting for girls than boys because girls have..[pointed at her future bosom]"
The parents just exchanged a look. I said, "I guess she hasn't seen a naked boy."
The kid interrupted, "I sort of have. I've seen girls in their underpants."
Right. Totally the same thing.
