Racquettball is one of those sports you can play by yourself and not look like a loner or worse. Solo basketball games make you look a little like a loner, and one-man football just looks plain silly. The hard part about you-on-you games is the score. I’m not exactly sure how you’re supposed to determine whether you’ve won or lost. I’m used to losing, so I just assume I’m continuing that trend. In racquettball, at least, I think the scoring must have something to do with how extremely exhausted you are after the match.
