I don't want to rewatch these some old Christmas movies again.
Why don't you want to watch the Christmas movies again?
I don't want to spend time watching them with my annoying family members.
I understand, but spending time with family members during the holidays is part of the experience. Allow yourself a break and know those movies are secretly a gift for you being able to do your own thing.
No, I can't stand being around them.
I understand how you feel, but it's important to spend time with your family during the holidays. I'm sure they'll be upset if you don't watch the movies with them. Maybe you can sneak out every few minutes to have some time to yourself.
