There are more, but those are the most frequent. I'm not even free to ask them, "Just how much reading and research on this process did you do before coming here to complain? What is it about this that you don't understand, that I've been trying to explain to you as simply as I would to a small child, or is it just that I'm telling you the truth and it's just not what you want to hear?"
That's work, though. Here's school:
"Did you do the homework?" If I did, no you can't see it. If I didn't, shut up, I don't want to hear your comments.
"How'd you do on the exam?" AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAARRRRRRRRRRRRRRRRGGGGGGGGGGGGGGGGHHHHHHHHHHHHHHHH! And that's if I did GOOD.
