I have never been close to one of my relatives. The only living thing I like is my dog.
We are having dinner tomorrow with a bunch of relatives and friends. My dad will pick me up at 7 pm but I don't want to go there.
The issue is all of my relatives believe that it is necessary for a person to be socialized and adopt the habits of most people. I don't want to adopt those habits because I like myself just the way I am. Also, my parents abused me when I was a little kid; both of my parents used to insult and beat me and they forced me to join their company.
How should I put it nicely that I don't want to join them at the relatives' dinner? I am trying not to lose my calm and argue with them one more time.
