I'm not going to my dad's wedding
What reason could you have for skipping your dad's wedding?
My dad is such a loser and an idiot.
I understand that you have a low opinion of your dad, but it is still inconsiderate not to show at his wedding. Stop judging people and show him that you love him by attending the wedding.
No, I fucking hate every one else in my family too.
I think you should at least let him know why you won't be attending then. It can be really hurtful to be socially isolated from your family, it might help to talk with someone about this.
