Sent invites for DS's 7th birthday to 24 kids over two weeks ago, party in a week and a half... only 8 replies! This happened last year and I had to chase (in some cases literally chase parents in playground and others via email) just so I could confirm numbers (in the end pretty much everyone came). I know I am not the only one in this situation.. why oh why can people not just send a quick response! I find it so rude (esp when you have to confirm numbers with party venue) AIBU?
