This is from my DH.
He took our two girls to get a toy. I had just had a discussion with my oldest(6) about how boys have a penis and girls have a vagina. I mean, she knew before but it didn't click in until after her hair was cut very short and was being mistaken as a boy. I digress.
In middle of busy store
DD(6) to Dh " Daddy, do you know how you can tell I'm a girl?"
dh,clueless and preoccupied "no honey, how?"
I think you know where this is going.
dd(6) loudly "Girls have vaginas and boys have penises"
cue snickering lady down the aisle.
Better him than me I say
ETA: OH! How I missed the restrooms part of the title, I will never know.
I've just had the usual "Mommy, you're stinky" stuff
