She's 7.
We were talking about Christmas and one of the things I said was to remember her Mummy works hard to get her all these presents. She was quick to protect that Santa brought them. I said he does indeed, but Mummy pays for the elves to make the presents and then she pays for the delivery.
She said "Why does she do that? Can't she get them herself from town? And that way I can choose what wrapping paper I actually want? "
Kids, eh?!
SIL now a bit peeved that I've said Santa doesn't pay and give presents from magical kindness. Oops.
