God works in mysterious ways - a nice way of saying "People are bloody weird"

Well they are, aren't they? :D I was in a lesson today, won't say which in case someone from there reads this, but have you ever noticed, especially in a mass lecture, that there are definitely different kinds of people. There's one or two people who sit at the front and nod enthusiastically to everything the teacher says, even if the rest of us would probably dig our eyes out with spoons rather than listen to it. Then there are other people who go one step further and actually verbally agree with the teacher. I once sat behind one of these "mmm"ers and I'm afraid to admit that after 14 lectures I could have poked her in the back of a head with a very sharp pencil. Then, there are the people who, for some reason, decide that they are, in fact, in a one-to-one lesson with the teacher and the other 86 of us are there for our health.
Today I was really annoyed because I have two such very special people in a lecture. One enjoys upping and leaving now and again, muttering under his breath loudly and laughing maniacally at the slightest joke the teacher makes. The other one must be confused because she seems to think she's my teacher. I asked the teacher a question today and I got a reply from her. The worst thing was she kept interrupting while I was trying to explain what I meant. Unfortunately she didn't wait for me to explain myself before talking over me so she didn't understand what I was asking and was in fact trying to tell me that you can't grow plants if a shelf is vertical. I kind of told her off though, guess I'm still that bit immature, whoops :D Well, maybe it's ok, I'm only 21 for goodness' sake. I'm not expected to behave nicely until I'm old, and I know a lot of old people who are rude anyway :D
I suspect I talk too much in lectures but at least I know when to shut up if I got something wrong :D Had to get it off my chest before I start sharpening pencils..
