I just got to thinking the other day about 'swearing.' As in 'saying what our society thinks are bad words, when under pressure.' Why do we do it? (I'm not against it, by the way—I do it myself—but just wondering why.) It's almost as if the words come unbidden. You drop a brick on your toe. What happens? You scream 'SHIT!' or 'FUCK!' even if you don't normally pepper your conversation with these words. Why? Where does that come from? It's not as if you have time to think about it. It's just automatic in many people. Funny.
