There are a few things that I don't do that make me different from the average guy - eat animals, believe in god/s, and drink alcohol.
I've been a vegan for several months now, and I'm really enjoying it. And it's been a few 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 other trait that makes me different than your average dude is that I believe in one less God than most people. I'm almost always up for a spirited conversation about religion, 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).
