Namechanged for my first ever AIBU post.
My understanding of RSVP is that the invited person responds to say:
a) yes please, I'd love to come
or
b) no thanks, I'm busy/can't be arsed.
I threw a small party for my DS recently and was pissed off that three sets of parents had not bothered to respond. These children didn't attend but I couldn't be sure that they wouldn't as I had no response. My DP thinks that maybe people only RSVP when it's a 'yes'.
AIBU to be pissed off with parents who do not rsvp to a party invitation?
