As part of the Daniel Fast, Bren and I have been giving up swearing too. While it hasn't been too difficult, every now and then, we catch ourselves usually when we hurt ourselves or we're irritated. Our substitutes tend toward the obvious: "mess" instead of sh*t, "fudge" instead of f**k. It's funny how even three weeks of forgoing the 'f' word makes it seem oh so vulgar now!
I wish I'd heard of this kid before though; 15-year old McKay Hatch started a no-cussing club (NCC) at his high-school here in Pasadena, after his friends started asserting their teen angst-ridden independence by sprinkling curse words through their vernacular. He told them to either cool it with the cussing... or hang out with someone else. Surprisingly, they chose to turn their backs on the spicy language. His friends now say that cussing is "verbal abuse" and it provokes violence. Interesting, huh?
And it's catching on. The kid told Jay Leno that he's got 30,000 members worldwide! I am so f'in inspired.
