I wasn't proposing that, and my other proposals were obviously half-joking. I mean, come on.
"Welcome to adult life" translates as "Look, little twerp, I'm a grown-up and you're not, so I know better than you. I
am better than you.

" It's a smug, condescending assertion of superiority over someone else to feed one's own pride, nothing more.
I fail to see how irritation over inconsiderate roommates is less mature than a complete lack of consideration for one's roommates. Either they're oblivious, which is hard to believe, or they're highly inconsiderate and therefore immature. They also often bring over friends and talk, laugh, and shout so that it's difficult to do my homework in my own room. They're stereotypical fratboy freshmen teenage bros who somehow managed to get on academic probation (that takes skill) and who are obsessed with partying, sex, weightlifting, and being loud. I've just been quietly grumbling about their inconsiderateness, nothing more. I clean up after myself, make no noise I don't have to, and replace the toilet paper, and yet
I'm apparently the immature one.
