So, I RSVP'd promptly to my cousin's up-coming wedding for me and FI. (I had to write in "declines with regrets," because the only options were to pick fish or chicken entrees, but that's beside the point).
My aunt (cousin's mother/MOG/married to dad's brother) called my father and told him how rude we were to decline so quickly and we couldn't have possibly considered it and, oh btw, the MOB is going to B-list people and us RSVP'ing early allows her to B-list and we are therefore facilitating rudeness.
They sent out STDates in January. FI and I knew then that we couldn't attend this wedding. I thought that RSVP'ing promptly would have been appreciated.
My brother and SIL, on the other hand, failed to RSVP at all. So then my aunt called my father and told him how rude my brother was for not RSVP'ing and didn't my brother know they needed a head count and what was wrong with him.
Meanwhile, my parents are (bafflingly) planning to attend this wedding. I have no idea why, but I look forward to the stories they have from it!
I'm gonna go with 'not my circus, not my monkeys.'
