I've asked that question a lot lately, and nobody ever says no.
People always have bully stories to tell.
Stories about bullies in elementary school. I've heard stories about high-school bullies and even a story about a college professor who thought that the best way to teach was by browbeating students. There are two things about this fact that really surprise me. The first is that while just about everyone agrees that bullies are annoying, difficult, counterproductive, and sometimes even dangerous, nobody actually seems to want to do anything about the steady supply of new bullies who seem to emerge on a daily basis. The second thing that surprises me is that the people I've talked to never admit to being bullies themselves.
