Dave, that was great! :-) Personally I don't like cursing. In my experience vulgarity usually indicates weak ideas, feeble minds, poor social skills, emotional imbalances or any combination thereof. So I do try to avoid it.
Being in certain company / situations tends to bring it on, though ... and hey, there's no substitute for a f***ing good emotional vent sometimes, either.
Cursing can be socially quite effective too - kind of like dropping a bomb - as long as it's reserved for those very rare and oh-so-special moments. If not, it loses that riveting "shock power" real quick. And no one really listens to you anymore.
At least I don't. I know which 'Catters curse regularly, and I usually find myself just skipping their posts, for example. Too bad, because sometimes they DO have something worthwhile to share!
