Exactly the kind of reply I'd expect from the type of person I described in the OP.
"You're life isn't as good as mine, you're just jealous!"
Grow up.
OK, I'll bite.
There is a certain amount of irony with you telling other people to 'grow up' when you have started a thread to throw your dolly out the pram with regards to students. I'm sorry that your student time wasn't up to your expectations, and that you had to live with people who were below you. That must have been hard.
Maybe, just maybe, you're not so perfect yourself? I think it
is a certain amount of jealousy on your part. Did you fail and are blaming your house mates for it? Did you not get on with them because they didn't want to sit around playing WoW (or equivalent) all day long and you did? Did they make the most of their experience and now you're looking back with resentment that you didn't? Didn't they like you for being a weeaboo?

Something must have happened to make you have this much hatred.
Maybe it's time to let go of this resentment and remember the phrase 'live and let live'? Students, and their associated traits (which are completely inaccurate and ill-founded - you get 'inconsiderate', 'selfish' and 'immature people in all walks of life) aren't going anywhere. You're going to have to deal with this pent up aggression someday. It shocks me that you have this much disdain yet have managed to live with
twenty students, and not once thought 'you know what, I don't get on with these student types, I'll not live with them' but hey, you wouldn't be able to moan about them otherwise, would you?
*feels dirty for taking the bait*
