Seriously he is correct about people who go around looking for fights, just keep your cool and never ever leave a party alone after an altercation with someone or a group.
Other than that parties are a blast 9/10 times people just socially drinking maybe playing ruit or beer pong or some type of card game like up and down the river or **** the dealer with music either playing or not (depends the ra's where i am patrol like crazy on Thursdays so we don't play music on Thursdays just a magnet for those assholes.)
So yeah don't over drink and make some small talk you don't really need to hold full length convo's but if that occurs have fun and ill stress it again pace your self being wasted might seem fun but if it happens to often more and more people might begin to avoid partying with you.
