I agree Soprano's is a great show. Only on DVD or HBO. It's just not the same when Tony says crap.
Back on subject, my fiancee smokes, my soon to be mother in law smokes. My uncle smoked and died from pancriatic cancer in 2006. The problem is they have to want to quit. I'm hopful about my fiance. He has mentioned he wants to and he had cut back some.
Good luck with your neighnor. I'm sure if it the subject is discussed as a conversation instead of a lecture it wil go over better. None of like to be lectured!!!
