Id10t,
If you’re going to be 'that person ', I would suggest you be proactive and send your sisters a message to the effect:
" My dear Sisters, I love you all and in hopes of maintaining that feeling, I am going to absent myself from the family get together. Each year seems to bring about a struggle among you to have everything go your way. It hurts to see people who I love so much being so unhappy at any time of year, let alone Christmas. My dearest wish for Christmas this year is for love and harmony within our family. I can't change how you feel. Hoping you can.
Love."
I have three sisters who are very strong women. Thankfully they get along. If they didn't, I would be damned certain to not be in the presence of more than one at a time.
Best
Les
