Kristy: I love cutting hair. People say to me, 'Oh, you're crazy, you're too talented to be a hairdresser.' I think, Hey, hold everything! If I like to cut hair and feel it's fun, then I'm going to do it. Just because I'm special in one area doesn't mean I can't go and pick up scissors and cut people's hair. And I think, Wow, I could have this, too, as a career if I wanted to.
Kristy: (Kristy's last public statement to her fans as of Feb. 2008, issued on Jan. 2001) A lot of people have wondered what I've been up to. I retired from my career after 24 years. My feeling was that it was time to play my biggest part - MYSELF! I must say that it has been the best thing that ever happened to me. So many fans are disappointed that I'm not currently acting, however some may not realize that the process I'm in at this time is necessary and vital for my personal happiness and well-being.
