My Pet Peeve (well one of them) Validated: I had to post this thread from the Chowhounds site..."Why do guests ignore the RSVP request?" As someone who loves to entertain, its hard when you don't know if you are cooking/planning for 10 or 40. I care much less about WHO is coming, than HOW MANY are coming. Oh well, the toils of being the hostess with the mostest.
