Maybe I'm a little soft for this....
I was a substitute teacher, but I quit, and it wasn't because kids were being loud and obnoxious. I can handle that, but it was because I was getting bullied by the students. Many of them laughed at my physical appearance...I couldn't take it. It brought back memories of when I was in high school and it happened to me daily. I don't want to go through that again, and frankly the shitty pay isn't worth it.
