If you are in the last year of highschool, have decent grades (in general)and a job. Then I think you have proven yourself a person with a good sense of responsibility, capable of making your own judgements regarding your future. Judging by your story, your step father is setting a rather bad example for you with his thin arguments, his disrespect for your property and his rudeness. A bit of mutual respect is (IMHO) a very important aspect of every parent/child relationship. But then again, parents will be parents. Instead of being happy that you are not on drugs, not an alcoholic or skipping school, they start complaining about games
It sounds like it's no use arguing with him, so just focus on graduating and hopefully things will work out. Good luck with your schoolwork, I'm sure you'll manage [img]graemlins/thumbsup.gif[/img]
