Sometimes the best possible thing to do is swear up a storm that sends old ladies and little children running and makes even the toughest of merchant marines blush.
Our society has a problem. We like to label things as good or bad, when in essence very few things are entirely good or entirely bad. Like sex...and ice cream...and swearing. A well timed and phrased "Motherf*cker" can be quite liberating.
And here's another thing that makes swearing so marvelous and universal, no matter what language is being spoken, you always know when someone is swearing.
Or maybe I'm okay with swearing because I know that I am quite capable of expressing myself in far more erudite ways.
