Such a delightful story! My niece is about your daughters age and last christmas we were having a conversation where she asked me why I wasn't able to walk around well (I have a disability) and I told her that my legs just don't work as well as hers. She asked me why and I said, "Oh, I'm an old lady." She thought for a minute and realized her mom is older than me and so she finally asked, "Are you dying??" I was like, DAMN, that interaction took a turn! :-D
Bahahaaaha, that's what they do! It's both amusing and terrible!!
