I'm sure I've seen a similar thread but can't remember the consensus.
I live in a semi-detached house in a naice, family area. My next door neighbours (attaches) are a family with two teenage sons.
I've noticed a strong smell of weed a few times in the last few months, in the garden eg if we are out there or have our kitchen doors open. We've just got home having left the windows of the living room, front and back bedrooms on the latch (so not even wide open) and as soon as we parked up in the drive I could smell the stench of weed, and the hallway/living room/front and back bedrooms all stink of it. Including my 3 year old son's bedroom. And our bedroom where soon our newborn will be sleeping as I'm 40 weeks pregnant.
I've closed all the windows now. The smell will go, obviously.
Should I say anything? I think it's actually the mum of the family (and probably one of the teenage sons too) as when DH went over there once to discuss diy work we had going on, when she answered the door the whole house stank of it. It seems to have today come out of the parents' bedroom window as we noticed that was wide open. She's a heavy smoker otherwise, but weirdly I very rarely notice the smell of cigarette smoke; I guess it's not as pungent.
I don't care what they do in their house, they seem nice enough people and were very accommodating when we had some noisy building work going on. But I don't want my own house to stink of it, nor have to have my windows right shut at all times.
