We have not heard from even one of the 8 kids, either yes or no. School is over, so my son can't ask them at school.
What do I do?
I am inclined to wait until maybe Tuesday and then email the parents saying something like, "We have not heard from any of you whether or not your children will be coming to Nicholas's party on Saturday. [Time and location] We would like to know whether to cancel the party. PLEASE get back to us by Thursday!" I feel very weird about doing this, though, mainly because I am freaked out by it even being necessary. Last year, everybody RSVP'd except one kid, who didn't come and then his mom emailed me weeks later saying they had misplaced the invitation.
We are really hoping to avoid having our son get all excited about his party and all of us work to get ready for it, and then having nobody show up!!
But if we cancel the party, we have no way of getting that information to two of the invited guests: the girl above with no info in the directory, and another whose mailing address is still good as far as we know, but her grandma never had email and her phone number had been switched to another person last time my son tried to invite the girl over to play. This girl lives with her grandma at the farthest point of the school's attendance area, so to come over here they have to take two buses, and I hate to have them make that trip only to find out we canceled the party--but what else can I do, if they don't reply to the invitation??
We would continue with the party plans for even one guest; they can still eat cake and play. But 2 people eating at a table set for 9 can't help feeling let down, you know?
