are you an adult?
wtf are you doing going to 'parties'?
take care of your responsibilities and leave 'partying' to kids who have no goals in life.
if somebody complains how you are at a party, the kid probably works all week so he/she can save up enough money to drink it away on the weekends and then save enough money to go on vacations to vegas... all while living in either A)parents house or B)shitty studio apt and either driving A)shitty car they can't afford to repair or B)financed Honda Accord they can't afford overall.
