I know mine has. I went back to my flat earlier this afternoon to pick some things up, I am moving out of there slowly, and was carrying a heavy box out to my car when I stumbled and dropped it on my foot. It wasn't too painful, thankfully, but I came out with a stream of expletives, most of them beginning with f. When I was a jw, even thinking those words would have filled me with shame. Now I'm out, they have, to a degree, become part of my vocabulary, and I don't feel even slightly guilty about it.
How about you?
