Haha one of my non-drinking sisters was said to be the drunkest sober person you'd ever meet--she was always so much FUN to be around! Unfortunately she was killed in a car accident on October 6th of this year, but she was an outstanding example of non-drinking fun without being a downer to her drinking friends. She always went out and had a good time w/o alcohol.
There are other non-drinkers in my house, and I figure more power to 'em. I don't drink a lot, and when I do it's not excessive, but that is just because I have a hard time sipping on stuff the entire night and enjoying it. I'm not against drinking, though, and I don't hold drunkenness against other people. When I do manage to drink more (haven't eaten much that day/taking shots) I am a silly drunk and I think it's fun
Other people can do whatever they want and I don't have a problem with it.
