I’m hosting my first child’s birthday party tomorrow. We have had about five parents text to say thanks for the invite but they can’t make it. Absolutely fine. There are 18 parents who haven’t bothered replying at all. I’m making some spare party bags just in case extra kids turn up even though they haven’t RSVP. I just think it’s so rude not to say either way. DP thinks you only have to reply to confirm that you are attending the party but I thought you’d say if you couldn’t go. What do you do ?YABU - only reply to confirm attendance
YANBU - confirm either way
