pretty sure I already know the answer to this, but...
Since I moved in (October), my roommate and I have gotten along quite well. Sure, there's been the odd "oops, I forgot to give you that message" or my randomly waking up during the night to too much noise to resume sleeping, but he's generally a considerate guy.
This past week, however, has been a totally different story. Last Saturday night he and his buddies were up literally all night playing video games in the living room, which borders on my bedroom. Kris and I crashed at I think 12:30ish and I made sure to say a deliberate "good night" to the gamers, aware that the chances that they'd notice on their own that we had gone to bed were slim. We each woke up randomly during the night; they hadn't turned the sound down but more importantly my roomie was yelling and laughing somewhat maniacally at this game. At around 4:45 am, I finally snapped and got up and told him to quiet down, which he more or less did. Later in the week, he's had friends over repeateadly, playing this game repeatedly, tying up the living room for hours, leaving garbage (literally) scattered around the living room/kitchen and making me feel like an outcast in my own apartment. I don't mind his having friends over, honestly, it's their collective disregard for the place and for me that drives me crazy. Also, on Thursday he left the apartment and left all of the lights on AND THE (empty) OVEN ON. I mentioned the oven thing to him a day later and his response was "Oops."
He's always been really good about locking the door to our unit, even when we're in it and it's mid-day, which if you've ever overheard the screaming matches that go on amongst the residents of the spot across the hall is a huge relief. However, I got in at about 10:20 tonight and the door was open. I figured he was doing laundry or had just stepped out for a minute, but I found a note wedged into my bedroom door that says "Please don't lock me out, I can't find my keys :( Rory". This is a guy who is regularly out until after 2 a.m. I have no idea where he is or when he may wander home, and I'm supposed to leave the door open while I'm sleeping? I didn't even do that when I lived in what was a safer building and with two other people; I didn't do that when I was staying at Kris' and there was me and two guys. Can I honestly be expected to leave the door to my apartment unlocked while I sleep completely by myself until whatever hour my roommate decides to roll in? And I get that he's a spontaneous guy and just does things at the drop of a hat, but is it fair for him to ditch the idea of finding his keys to go out wherever and leave the place open to the whole building, with ALL MY STUFF in it?!?!?
I'm half-convinced he made a New Year's resolution to become a shitty roommate. He honestly has been great up until now.
