For years, especially when raising my kids, I didn't swear. About 7 years ago, I started cussing constantly. It got pretty bad. My kids noticed. My husband noticed and decided to join me in the cussing. It was fun. Now I'm back to rarely swearing but I do have my moments. I think I cuss more when manic. Statistically, I talk so much, a swear word is bound to occur due to the sheer volume of words I spew at that time. I'm very expressive and sometimes nothing expresses like a good ole swear word.
