D.) Not enough information given
I mean, seriously, there's so many variables.
Does this "friend" have a will? Am I in it? Maybe I might push cigars on him as a means to an end.
Did his girlfriend ask him to stop smoking? Is she hot? Could I possibly rat him out, then score the rebound with his "soon-to-be-ex" hot girlfriend? Lowdown, I know, but sometimes you gotta do what needs to be done.
