A few things that make me different than the average guy:
I've been vegan for about a couple of years, and it's been a several years since I've had a drink of alcohol. If your diet is different from mine, or if you enjoy a drink every once in a while, don't let my weird rules scare you away. I'm perfectly comfortable around drunk carnivores, and hopefully you'll be just as comfortable around a sober vegan. :)
The third thing that makes me different from your average dude is that I believe in one less diety than most people. I try to be very respectful of other's beliefs, but if you put a higher value on Faith than Science, then I hate to say it, but it probably won't be a match made in heaven (pun intended).
