I live on the fourth floor of a building that's shaped a bit like a T, and I live on the inside edge of the top of the T. One of my neighbours, who lives in my side of the long edge of the T, on the second floor, has recently (within a couple of months) started smoking out of what I can assume to be his bedroom window.
Now, I like to keep my window open all the time (including in Winter!) to get fresh air, and the cool breeze helps me sleep. Unfortunately, the smoke from his cigarettes drifts all the way up to my window, and fills my room with the smell. Bearing in mind I am a student in a shared flat (in a non-student building), I spent most of my time working in my room instead of shared spaces, since that's where my desktop is.
The problem is that a) I don't like the smell of cigarettes, b) I don't really like the idea that I'm breathing it several times a day and during the night; he does it quite a lot and c) when he's finished he throws the still lit cigarette out of the window into some grassy vegetation growing on the rocks below; I can't help but think this is a major fire-hazard, but I could be wrong. Now, I'll add that I've never spoken to him or met him, and technically his part of the building is an annex that I actually can't get to anyways.
How am I able to ask, politely, if he could please move to the front of the building (where there is only tarmac outside) or go outside to smoke (and stop littering) where my only means of communication with him is out a window, across two floors? I don't know what room number corresponds to the window, as I can't get into that part of the building.
Just to add, I can, of course, simply close the window whenever he does it, and I do, but that's a waste of my time and relatively annoying, and obviously, when I'm sleeping or just wake up in the night, I hardly want to get up and wake myself up completely to go and shut the window, only to need to get up again to open the window later when I can't sleep as well.
