@BorisKitten,
Alas, BorisK, you're behind on this, I swear moderately often, more than polite. (It's from my swearing deprived background, you know, later aroused by real life..) I have friends and relatives who never ever swear, many of them english majors. But I was primed in a laboratory with a boss who swore, and it was comforting, mostly, and, of course, he didn't over use it.) Overuse, tacky.
