Rude People ruin get together

Yes, the old Christmas **** shows........
This year, we were going to go to the sister in law's place, but she got into a mood last Sunday and called it all off. She even threw the frozen turkey at her daughter across the room and took down her tree and decorations. Then she proceeded to post a lot of crap on facebook to all of her friends and relatives as well as call everyone she knew that night to basically say ''f'' off and leave her alone.
Then on Wednesday, she got her husband to put the tree back up and decorate the house again, and Christmas dinner etc, are back on.
She called us up and re-invited us, and i said no, we already bought a turkey etc. and were staying home.
That was the third time this year she called Christmas off, then i told her 3 strikes and you're out. We didn't have the time to wait and see if she changed her mind again. Then it would probably be a lot of arguing at dinner anyway.
Now get this, she then called us a-holes for wrecking Christmas!
What a freaking head case psycho drama queen this year, but then again, she always has been into the drama.........
Consider yourself lucky!

Get her some therapy for Christmas
