OP, I hope you don't mind if I steal your talk.
I blew the whole black/white talk with my kids. Now when they describe someone to me they say they have brown skin because I had a meltdown the first time DS described someone as black. I was trying to explain that we don't use colors when talking about people. I thought I was getting it right, but now I have just made them think it is wrong to say someone is black.
Anyway, I hope to get this talk right. Your way of phrasing it sounds great to me.
Thanks!
