So here's one for the record books. I just found out that my XMIL (my kids' grandma) who's son I've been divorced from for 20 years, as been telling a fabricated version of a story for the past .. 20 years I guess! When DS25 turned 3, she had a party for him at her house. At said party, she and I got into a fight (she is the world's most difficult person, she has histrionic personality disorder) and she picked up my son's Elmo cake and threw it at the wall. Of her own dining room. In front of her 3yo grandson who's birthday it was and who hadn't even had any of the cake yet. SO! After all these years of blissfully never seeing her, I just found out that she's been telling everyone, including my kids (and re-telling it over and over at every family gathering for the last 20 years ) that it was ME that threw the Elmo cake. Jesus. I just told my son not to argue with her about it, let her tell her story... just know.. I didn't do that. She did.
