OK, I know this is weird, but I'm kind of impressed with how fast people have RSVPed. Some of them, my family warned me wouldn't RSVP at all, and it was a surprise to get them, with a nice message on the card. I kind of want to thank them, via private message on Facebook or private email, for responding so soon, and also say that we are sorry they can't make it/are so excited they will be joining us.
Is that a weird thing to do? For those who aren't coming, will it look pushy that I'm thanking them? My anxiety makes me imagine a worst case scenario that my cousin's wife will think I'm being gift grabby by doing that. Is that a rational fear?
