I think I'm cross enough at the moment to brave AIBU...
We live in a block of flats, love where we live and aren't planning on moving. Neighbours moved in downstairs a few months ago. It became immediately apparent that they are a) chain smokers and b) fry everything. They must realise these are smelly habits because they leave their windows open all the time even though it is cold here.
We share the venting system when them so our loo smells like a chippy/old pub. I dislike it but that's what you get for living in a flat.
My major, major rant is that they smoke in their kitchen/fry there so if we have the windows in our kitchen open (we both like a lot of fresh air) our flat quickly smells very strongly of either to the point that visitors have commented. I mentioned it to our landlords as they are semi-friends and I didn't want them to think it was us (strictly verboten in our T&Cs). They then spoke to our neighbours' landlord as they thought he wouldn't rent to smokers (I didn't speak to them with the intention of getting NBs into trouble but us out of potential trouble as it really smells like it's us - LL has since visited and commented on the smoke).
This morning I was taking a shower and the room smelt like smoke. I assumed it was someone on the road so left the window open to air the room. DP has just gone in and remarked that it smells. Our bathroom - and bedroom for the window was open there too - smells like we have been smoking in the room. I leant out and, sure enough, downstairs have their windows open and must have been chain smoking all day to build up that kind of stink in our flat.
My irrational fury wants to march down there and tell them how it is affecting us. I know that would BU but AIBU to be hacked off that, if they clearly think it smells in their flat, their solution is not to smoke less or fry less, but to open their windows and inflict it on us? We chose a non-smoking flat for a reason and our LLs impose a non-smoking rule for the same reason. Why should we be impacted more than them?
[Disclaimer: I have a possibly irrational hatred of smoking as my maternal GPs both died when I was a baby due to GF's chain-smoking habit (emphysema & lung cancer) that also made my DM very very ill and means she still catches every lung infection going today. I know they have as much right to be in a public space smoking as I do as a non-smoker and that they have a right to smoke in their private flat - it's the open windows that bother me.]
