Next door to our house is a shop with a flat above, which means our bedroom is level with the living quarters. About 6 months ago, a new neighbour moved in. We are in nodding 'hello' terms. He is quiet and an otherwise good neighbour, but has a fairly severe weed smoking habit, which we can smell in our bedroom at all hours.
He must smoke all day, and it is extremely pungent, as it comes into our room as early as 6.30 am before he goes to work, and last thing at night.
I like the windows open, as am peri menopausal, and often boiling hot, but the smell is vile.
I have no moral objection to his habit, other than the stink, which is affecting us daily. (we also have pre teen DC, who I would prefer we're not exposed to this constantly)
AIBU to knock on his door and ask him to keep his windows shut while he is smoking, or should I put a note through? He could completely deny it's him - I have never actually seen him smoking, but it's very obvious where it's coming from.
