I have a few choice family members who feel it unnecessary to RSVP to ANYTHING. Both guilty parties are families of 5 and of 6, so that's a good table or 2 at the wedding. They've historically failed to RSVP and will either only respond if followed up with directly, multiple times, after RSVP dates have passed, or casually mention 2 or 3 of them will show up. I even once got a 'i'll try to make it' like that helps. If they weren't immediate family members, I wouldn't even invite them...but family politics blah blah blah. My sister had a destination wedding and they didn't even bother RSVPing for that!
How do I put on my RSVP cards "no response means you're not coming"? I honestly don't think some of these buffoons get it. I'm not dealing with it, or chasing them down for a response. I don't care if it's rude, I think it's more rude to not RSVP.
So, any suggestions on how to be politely aggressive?!
