Tennis was the only sport I used to like. Honesty compels me to say that I mostly liked female tennis, and my motives were not exactly pure ( I wasn't always Catholic ). I had a crush on Martina Hingis for some reason although I don't know why now. But I also liked female tennis because it wasn't as blindingly fast as male tennis, it had some elegance in the days before Serena and Venus Williams, which is when I lost interest.
I also live in Manhattan Beach where a fairly big all-female tennis tournament, Virginia Slims, is held.
I think what I liked is that it isn't a team sport. The individual is out there alone, and whether they win or lose is not just about talent but about personality, about temperament. Each player had certain character flaws that made them interesting to study, like they would have natural talent but get possessed by vanity, love of limelight, etc. Or else they had an anger problem, or maybe they were a cold-blooded machine...
