OK, I'll be honest from the start, and say that I probably annoy them as much as they annoy me - but we've only been back for a week and it's already depressing me. We were all thrown together at the start of the year (I didn't know any of them before the start of this year), so I don't know if that's part of it.
Out of my 5 flatmates, I only truly get on with flatmate 1. All of the other 4 have something about them that bothers me. Flatmates 2 and 3 are really nice and we can get on well, sit down and have a laugh etc, but my problem with them is that they are just really loud, particularly quite early in the morning at (say) 7am. They just have really loud voices and the walls are paper-thin; they just don't seem to acknowledge that there are other people around them. One of them also plays her music really loudly (to the extent that last term someone from the flat above pushed a bit of paper under our door asking her to turn it down), although she's got better recently. However, compared to flatmates 4 and 5, I can cope with this.
Flatmates 4 and 5 are just really cliquey with one another. I can understand being close to certain people, but when it makes other people feel excluded, I think that's just a bit rude. Flatmate 4 and I got on at the start of the year but now I have a feeling she looks down on me (she's a gym bunny who apparently never eats anything unhealthy or watches TV, whereas I am...not, lol). Apart from that, though, and her cliqueiness with flatmate 5, we get on pretty well, can hold a civilised conversation etc. I try my best to be friendly because after all, I do have to live with them.
It's flatmate 5, above all of them, though, who gets to me the most. At the start of the year we were OK - never bosom buddies, but OK. But then he started playing his music/TV/films really loudly at really late hours, like midnight onwards. At first I would just get up and ask him to turn them down because I was trying to sleep, and to be fair, he did comply at the time. However, he just kept on doing it, and one night I just went over the edge and wrote a slightly sharp note on the subject and pushed it under his door. And, again to be fair, he has been better about this recently. However, he still insists on leaving on the corridor lights all night (apparently he's afraid of the dark at 21, which I think is seriously wimpish), which really disturbs me as not only does it shine under my door and wake me, but is also really bad for the environment. Flatmate 1 and I also think it's really bad for the environment, as well as being totally senseless, to do the other thing that he's often guilty of doing, which is to leave the windows open in the kitchen when the heating's on. This (I hope) won't be so much of a problem now with summer coming, but the fact that we're a ground floor flat means it's a security issue all year round, and I'm fairly certain that our fire extinguisher got stolen this way. It's mainly flatmate 5 and one of the first two female flatmates that I mentioned who keep doing this, and it annoys me that they can't see that it's a security risk.
Admittedly I probably didn't deal with this very well. Some of the issues were raised in a flat meeting, and for a short time afterwards people made an effort to close windows etc., but they don't now, and I know that calling another meeting won't make a difference. Now I just seeth inwardly and close the windows in the kitchen every time I come home from work (seeing as nobody's in there at 11pm and all!), but the issue of the lights in the corridor is something I acknowledge that I dealt with badly, although flatmate 5 himself is no saint. After a while I just cracked and would get up every time he left the corridor lights on so as to switch them off, but he would just switch them on again. I should have acknowledged that I was fighting a losing battle, but I didn't, and I left a note on the lightswitch telling him to just turn the damn light off. He left me one back that was equally courteous (not), and relations have been strained ever since. At the start of the year, flatmate 5 and I could happily have a conversation with one another. This was then reduced to just a hello, and then just a grunt (on his part). I still say hello to him when I see him, but I don't even get a grunt now - and in most civilised societies I think this would be considered quite rude. This is exacerbated, in my mind, by his closeness to flatmate 4 (they are close to the extent that flatmate 1 thinks that 4 and 5 would be together if 4 didn't have a boyfriend).
As I said, I acknowledge that I probably didn't get it right. Now I just put a towel at the bottom of my door to block the light, but I still worry about the environmental impact, and feel that he should do his part (just because all of our bills are included, it doesn't mean that people should lose their social conscience).
This all sounds petty when written down, but when rolled together it really gets to me, simply because it all makes my living experience here utterly unpleasant. I can also accept that part of my feelings of misery may be the fact that my boyfriend and I currently live in different countries, so I can't just escape to his whenever I feel low. We've never really talked about it, despite the fact that I think everyone can feel factions developing, and to be honest I almost don't want to because I have a feeling nobody except flatmate 1 will be on my side.
Sorry it's so long, but if you have any advice to offer, let me know. If you got to the end of this you deserve a medal!
