This morning at the gym, I was next to one of "those people" on the elliptical machines. He was someone who obviously does not watch sports, but prefers Sports Center. Every clip he watched was met with an "Oh, no!" Or, "Oh, man!" He was not as vocal as a guy I watched a few years ago, who actually yelled at the refs and kept saying "Did you see that?" to people. It took all I had not to shout back "Yes! I saw it! LAST NIGHT!!!" The guy today was also a sweater. I have observed him before, and would not have chosen to be next to him, but he came up when I was halfway through my time.
There are bullies at the gym. If you are on a machine a bully wants, they stand uncomfortably close until you finish. In the locker room, the bullies are old ladies who walk around naked. They make sure they tell you when your towel is on the wrong hook. They hog the benches. They hang with their gangs in the sauna room. They get what they want because, frankly, talking with a naked old woman is less than pleasant.
