When I was a young man only rough, working-class people swore in public. Which suited me fine since I was a rough, working-class guy.
As I moved up in the world I really enjoyed shocking people with my coarse language at dinner parties.
Now everybody swears.
I've tried substituting the C-word but somehow it doesn't have the same effect. As the permanently bruised shins my wife has given me testify.
So come on guys. The English language is part of our heritage. Don't devalue it. Next time you're in polite company, for Christ's sakes watch your fucking language.
