Well, this was out of necessity. A year isn't so long . . .
You can make it. It may not be pleasant and you may find yourself spending less time at home than usual if things get bad, but you can make it. If you haven't lived with roommates in a while I advise you to address conflicts non-passionately but with immediacy. If you have, then you know what you're doing and you'll be fine.
I wish I had a good story! The dude is nice enough, he just... gives me teh heebie jeebies. He walks around super quietly all the time and has a strange gait, and these super dead eyes and smile that make it hard for me to look at him. Like... he's not smiling, it's a totally neutral expression, but his lips naturally curl just slightly. he also has the most unsettling voice I've ever heard. It's deeper than it should be for how he looks, but it isn't a deep voice, and for some reason, it's extremely soothing, but in a way that my brain doesn't take it as a relaxing sound, it immediately tells me "FUCKING RUN."
