DD's birthday is coming up and because of various commitments the only day free to have a party for her and her schoolfriends that's near her birthday is Father's Day. We're only inviting 4 friends to make it a smaller do and intending to give out invites tommorrow but I'm now panicking that no-one will come because of the day. WWYD - have it then anyway and hope they don't all say no, or have it after school on her actual birthday, which would be very awkward but just about do-able?
