I don't swear a lot. It's a bad habit that I never got into. My parents would say shit, and I only heard my dad use the "f" bomb once, and it was because a car almost hit us. When I was a teen, my friends and I would swear to be cool, but once I starting working, I realized you can't talk like that in a professional environment. And it wasn't something I could do around my parents back then or even now. I think it's a habit for some, but other people seem to be able to turn it off and on, which may show they're using it for shock value. They won't swear around their parents or at work, but around their friends they do it all the time; they're able to turn it on or off.
