Some unsolicited advice

For stupid people: People do not think. Or they are inconsiderate on purpose. If you are the first person into a lecture theatre, do not sit on the end of the row. Because then, either people have to climb over you, or you have to get up. So much effort. Just walk a few extra steps to the middle of the row of seats to avoid all that hassle.

Because, really? It's not a plane. There are no 'good seats'. You're here to learn. Just do it.

For disinterested people:
The girl sitting next to me (but one seat away, you know how it is, god forbid you actually sit next to someone) spent the who lecture reading. Not lecture notes, not research, but a novel. Now for all I know, it was a compulsory text for another class. However, the fact remains that she did not take one single note from the lecture, and I doubt her powers of concentration are good enough to enable her to take in what she was reading and the lecture at the same time.

Do you not think we pay enough to be going here, that's it's a school it's even a little bit hard to get into and therefore people who would actually work hard would love to trade places with you, enough that you could actually spend 50 minutes to listen to the person you're paying to hear?

For bus driver people:
So you're at the bus-stop on campus, you're wearing a backpack, your arms are full of folders and textbooks, and what does the driver say? "I need to see a student ID." WFT?! Like I would seriously impersonate a student to get a cheaper bus ride. If I was going to impersonate someone, it for sure wouldn't be someone who has to take the bus.
