Actress Kristin Davis finds it impossible to watch past episodes of her hit TV show Sex And The City, because they depress her. The star, who played CHARLOTTE YORK on the show, refuses to watch the reruns because she doesn't want to revisit the past. She says, "We're on all these different stations now - WGN, TBS, I can't keep track of it all. "It would be depressing to watch it, like going through your high school yearbook, like living in the past. "Sometimes I'll be flipping channels and I'll see a funny little promo and I'll see a little joke and I really like that because I can enjoy it in a miniature form. "After seven years you can't remember every episode, so I'll think 'Look at what we're wearing and look at where we are!'"
