My almost 8 year old DD has been invited on a play date with a girl ("Lottie") in her class. They aren't really friends - don't dislike each other as far as I know, just both play with other people.
DD doesn't want to go - she's quite the introvert and doesn't feel comfortable with people she doesn't really know. The invite came from Lottie's mum who I really get on with but have never really spoken to outside of school gates and birthday parties. I think maybe the invite is possibly more because we as parents get on more than the girls, but now of course DD really doesn't want to go.
How do I word my reply to Lottie's mum?! I really want her not to be offended and to keep her as a potential friend - but every way I word it is rubbish!
