Important background - neither DF or I have personal Facebook accounts. I have one for work and that's it.
Tuesday - DF and I get a gift card in a congratulations on your wedding card. But it's not from someone invited so we were trying to figure out who it's from. Finally figure out it's some random cousin of DF. Thanks FMIL for the help there!
Wednesday - I mailed the thank you card from both of us. You know, Thank you for the well wishes, blah de freaking blah. DF signed first as it's his family.
Friday - DF gets a crabby, weird voicemail at why won't he acknowledge cousin from her mom/his aunt - who is also not invited to wedding. DF had to work late so didn't pick up the voice mail until yesterday.
Saturday - DF calls aunt to figure out what is going on, had to leave a voicemail. That was about 10:30 am, didn't hear anything, figure maybe we got the gift card late and our thank you card was delayed.
Nope.
Sunday/today - I answer the phone. Cousin is so upset she can't call, so her mommy is calling for her. Aunt is just furious that we had the audacity to MAIL the thank you card. We were supposed to just say it on Facebook. I, in all my less than nice manners, pointed out we don't have personal Facebook and if her bratty child wanted public adoration for sending us a gift, she can post the fucking thank you on Facebook herself. We got a physical card, we sent a physical thank you. Aunt hangs up on me. Calls DF's cell. He needs to sign up for Facebook, publicly thank his dear cousin and apologize for being so rude as to not do so earlier. He's just looking at me like WTF? and tells Aunt no, and she's just proving why her crazy ass wasn't invited.
In the three hours since, she's called FMIL twice and apparently had a crying fit on Facebook over how horrible we are to not thank her daughter and to not invite family to a wedding.
I'll remember to never send them a thank you card again. We still aren't inviting the crazy to the wedding.
