I'm going to tell my mom I won't be going home for christmas
Is there a reason why you won't be going home for Christmas?
I hate my parents.
It can be tough dealing with family problems. Some families never get along no matter how hard you try. Are your parents expecting you home?
Yeah, they think I'll be there.
If you waited until the last minute than your parents may be more upset with you cancelling. If you know that this visit will end badly, it may be best to not agree to any future holidays.
