I'm going to do something tomorrow I probably shouldn't
What are you planning on doing that you shouldn't do?
I gotta get even with my family
I can understand that sometimes you might not like your family, but you shouldn't do something you'll regret. They are your family forever and you will miss them. I think you should sit down and talk to them about how you are feeling.
I'm not going to do that. They never listen.
What are they doing that is making you feel this way? Maybe I'll have a better understanding then.
