Nearly anyone is abusive, if allowed to be. Getting hit in the nuts really hurts. The older somebody gets, the more that they smell. Authority figures are the most flawed of all humans, and will inevitably pick a few people to encourage and praise, and a few more to tear-apart and destroy. That's where I usually come in.
Most people are followers.
I'm not like most people. Taking showers in front of a bunch of other members of the same sex, is kinda embarrassing. Always keep your underwear clean, somebody, someday, might see it. People are hypocrites. Most people are all the same.
