Sorry you have such an unpleasant family. I don't mind mine so much even if there are a couple of odd ducks in the bunch. At least not enough to disown them over turkey, LOL.
You’re lucky. We have the drunks, the sluts, the know it alls, the name dropper who doesn’t know anyone, the holier than thou, the better than everyone else, etc. Put them all in the same room at the same, uh, no. A few years ago, I decided to stay out of their way so sat off to the side and observed. Eye opening.
