I haven't sworn since I was ten years old, and that was at a family reunion playing volleyball. I just don't swear. Even in my head. UNTIL about 6 months ago. I started swearing in my head. 97% of the time it was the saying "you make my life hell," to express internal road rage. Yesterday my mom spent a few hours in the kitchen: cleaning, cooking, and preparing for the missionaries to come over for dinner. Well they never showed. And they never returned our phone calls. So I announced at the dinner table that if it wasn't for those damissionaries...blah blah blah.
The point is not that I forgot what I said after I swore. The point is that it is refreshing. And it adds humor and ease into strict lifestyles. And it's only funny in very small, rare occasions.
