Guys, to be fair, all the OP has done is vent frustration. Yeah, it's a fact of life that you have to deal with authority figures you'd rather not, but that doesn't mean you can't dislike it or have a bitch about it because it sucks. And that's all the OP has done. >_>
Agree with Dervish's point on empathy, though. Had an interesting chat with my teacher about the sorts of scary crap teachers have to deal with at times; not always the cushiest job, to say the least, and being a sub only makes it worse.
