Being Single Sucks

Normally I don't mind being single. I've been single pretty much my entire life (there was that year or so with Dennis, but for the most part single). I've come to accept this and don't mind going on vacations by myself (New Zealand was great - if you don't count the problem at the Sydney airport); I go to dinner and movies by myself. This is all fine. But, today I went for a rock climbing lesson. I did not realize that this is not a sport you can do by yourself. In hindsight, I should have realized, but I just decided to try it out. They didn't say anything to me when I signed up by myself (which I really think they should have). The first part was fine, I figured out all the knots, figured out how to hook everything up. But, then everyone else in the group got to climb. I didn't get to climb because I didn't have anyone to belay. I did get to belay, though. The instructor had me practice while he climbed. So, I have no idea if I actually like this sport that my brother speaks so highly of.
