Swallow your pride, tell him you're sorry (assuming that he's not being completely unreasonable...you're not exactly being specific here), and try to avoid further confrontations. Risk of random, crazy [censored] from your neighbor is enough to justify a relatively minor concession. If we haven't learned to avoid letting our egos get in the way of making peace, then Biggie and Pac will have died for nothing.

Edit: YOU'RE SMOKING ON THE EDGE OF THE PROPERTY?!? Screw this guy-tell him to complain to the property manager if he doesn't like it, but your right to not have to walk for miles to smoke trumps his right to keep his window open, or at least the two are even so he should be more considerate.
