Drinking is a touchy subject. Throughout high school, I absolutely HATED some of the people who drank, and with good reason, because they acted like morons. But recently I've realized that it's just not good to hate someone for something so trivial. I'm a junior in college, and while I don't consider myself an alcoholic, I will have the occasional drink once in a while to lighten up and take some of the stresses of school and work off.
Having a couple drinks just helps me enjoy the company of the people around me more. I went to Ohio State this past week for Summer Sanitarium, and stayed at a friend's house for the night. There were about 8 or 9 people there, and I only had a couple beers, but I had a good time with everyone, even though I had never met them before. I'm almost positive if I had the same attitudes about drinking that I had before, I would have not had a very good time.
Don't let stupid drunk people ruin something for you. I don't see any problem with people having a few drinks and enjoying each other's company.
