Rather than hanging out with my friends I want to watch a WWE shown.
How will your friends feel if you choose to watch the WWE show rather than hanging out with them?
I couldn't care less about their feelings. I find my interests to be more important.
It's okay to spend time alone doing what you enjoy from time to time. If you had plans with your friends you really shouldn't just cancel at the last minute though. They'll feel like they aren't important to you, and it could damage the friendship.
I don't think they will care.
Cancelling on your friends at the last minute is rude and you should be more respectful of their feelings and how cancelling could inconvenience them. So long as you give them enough notice, it's perfectly reasonable to want to spend time at home doing what you enjoy.
