Have you ever noticed that guys who don't wear shirts are very often criminal sociopath/unstable types, that are secretly dirty underneath the tennis veneer? Bad calls. Too much testosterone for their own good. Too many fights. Fist fights/verbal abuse, female abuse. Too many passes at girls that are too young for them. Braggadocio. They mouth off about having beaten you? They think they are better than they are, and are insecure in their own alpha maleness? Too bad the women aren't allowed to do the same! Now I could deal with a mouthy topless woman out there, bragging about how she beat me, far more enjoyably, than a mouthy braggy man! Ha, ha. For all you shirtless guys out there, I am on to you.
