So we're at the beach years ago. Daughter is 3-4 yo, son is about 8.

We've been telling son to tie his swim trunks all week, and he still doesn't do it. He is a skinny kid and everyone but him can see that if he get hit by one good wave, the trunks are going to end up off the coast of Ireland someday.

Mom gets annoyed with his poor listening skills and pants him right there in the hallway of the condo. He squeals and yells "mooooommmmm!" then pulls his trunks up and ties them.

Meanwhile, daughter starts pointing an laughing. She says while giggling "I saw [brother's] penis!".

I told her "do me a favor baby girl. Whenever you see a boy's penis, do that again. Just point and laugh. It will serve you well through life."

Maybe Brittney had a similar experience and she was just responding to some strapping young man's advances. Or not.
