So I'm going to my first real high school party today, parents not home, alcohol and cigarettes, ect.

Not only that but I'm only going with one friend I'm only somewhat friends with. I'm also going into a group of people that I don't really know too well. So I'm not quite sure what the best course of action for this would be here, I really don't want to be that guy that just sits on the couch with a beer in his hand and watches the TV or something like that and I was hoping that maybe the kind people of reddit could help me.

P.S. Im not looking for girl advice specifically but any advice in general. I wasn't quite sure where to put this and since this is usually the more 'extroverted' subreddit I thought the people here would be able to help me the best.

Thank you!
