I developed a greater respect for our teachers. Between classes, I did presentations at the other grade levels, went out for recess, and ate lunch with the kids. Those are difficult to work because intoxicated people just don't understand how their actions can be dangerous. And groups of drunken people can get way out of hand. Same with the Klan rallies over the past few years.
Emotions run high.
People aren't always rational. Resorting to tear gas to break up a crowd is a pretty tense situation. I learned early that I had to be careful how I shared the details of my job. But it was a great time, definitely, for me. It was a really difficult decision for me to leave that job.
