So we have a new next door neighbour who I would describe as a chain smoker ie he is outside often from 7am until after 10pm, every half hour or so (at least he seems to be when I am home to notice). The issue is he smokes underneath my son's bedroom window and my son has now developed a cough (could be unrelated I accept this). Is it appropriate to ask him to smoke further away from the window and do I really have any right to comment on this since he is on his own property? We obviously close the window but it's tricky because that means no fresh air in the room as the smoking is so frequent! Thought I would gauge what you all thought about possibly having a friendly chat with him and explaining the issue to him!
