It would be awkward hanging out with a 13 year old, but it would be awesome to have him close. A one legged guy would be interesting to be real friends with, but cool at the same time I'm sure. And the other guy lives a few states away from me, but he's my age and it would be epic if he lived by me.
I think one of the reasons you get so close to guys you meet on the internet though is because you actually don't have to deal with each other in real life. It's much harder to find flaws in a person over the internet. I really don't know. It would be cool to try out for a week in the summer or something like that.
