You see some pretty vile practices in evidence out in public. People spit on the sidewalk, go through the garbage and just plain smell awful. I recall walking to a party in a neighborhood of poor reputation and being asked for a cigarette by a man in the act of urinating in public. That was what you call a two-fer of unpleasant behavior. None of those are very subtle offenses to the sensibility, I think that we all can agree.
I thought to write on this subject after consideration of a significantly more subdued crime. I guess it is more a case of being insensible than insensitive. Undoubtedly you have seen the same thing, maybe without noticing it or finding it remarkable in the least. What I refer to is the act of placing a new, unlit cigarette behind the ear with the intent to smoke it imminently. I see this quite a bit on the subway and in other places where smoking is forbidden.
