Well, I have often said, tongue in cheek, that one of the drawbacks to home schooling was that the girls do not know as many swear words as other kids their age.
It looks like it extends even to harmless euphemisms for body parts.
The girls dressed up their Barbies with some old Barbie clothes I had. I informed DD10 that what she had as a hip-belt / low cumberbund thing should be worn "around her boobs" (my words)
"Her what?" (her words)
"Higher," I said. She looked at my in confusion. Then after a few seconds she said "Oh, you mean like a bra?"
Now, I don't have a problem with the word "boobs" personally. It just feels nice to know that she hasn't had any body-part discussions with other children.
