I'm going to refuse to come to christmas
Why don't you want to go to Christmas?
I'm tired of my family and want to chill out that day
There is nothing wrong with wanting some alone time to recharge. It can be a lot being around family a ton.
I didn't say I won't join them, I just don't have the right mood
Okay, so maybe you take that day to relax and you celebrate on Christmas Eve or New Years.
