Also, when you ask how to change a registration for a course, and I tell you how, don't send a whiney email back asking "But why? Can't we do it this way?" Because the answer is "No, you can't, because I said so!"
And then there's the ever-present annoyance of supposed academics who seem to lose all sense of grammar and punctuation when it comes to email. As my coworker said, our lives would be a hell of a lot less stressful if we were allowed to just ignore any email we had to read more than once in order to understand the actual sentences. I'm not even mentioning the lack of greetings/closings, because that's a lost battle.
I really hate people sometimes.
Edit/ Just to show you how annoyed I am, I just stuck out my tongue at my Outlook. Because yes, I am that petty.
