I'm a pretty quiet guy in person with what you'd call a tad bit of social anxiety. Awkward, I believe, would be the right word to describe myself to a stranger. That doesn't mean I completely avoid people though. I have a few good friends with whom I play video games with, go to the bar with, watch awesome TV shows named Dexter with, etc. Consider me a late-bloomer. I may be closed off when you first meet me, but I open up with time.
I've never been a huge fan of interacting with large groups of people, i.e. big parties, clubs, social events, etc. I tend to stick to small groups of people, maybe myself and two or three friends just hanging out, playing a board game, or going to the bar and having a few drinks while we chat and play cards. I'm 420-friendly, but don't smoke much, if at all.
I'm not a big risk-taker, as most of the spontaneous decisions I've made in life always ended badly. Of course, I still can be adventurous every now and then, given the right company and motivation (read: ALCOHOL).
If you haven't noticed by now, I do enjoy partaking in a good alcoholic beverage or three every now and again. It helps me loosen up and really helps me start conversations when I would otherwise be too shy/nervous to speak up. Don't judge me :P
