Sent out party invitations to everyone in DD's class, thats 20 kids, about 2 weeks ago. I've had 6 replies. Am bl*dy steaming as it happens every year and the ignorant fckers blithely turn up and expect food/party bag. I know I've invited them, and I dont begrudge buying the food/treats at all if I know it wont be wasted, but I object to buying party bags and food for 20 when only 10 turn up? what can I do? I'm considering sending a polite reminder to those who havent replied, hoping to shame them into letting me know, or making sure those who havent spotted the original invite know the party is happening.
