I've got a lot of letters from prison. Lost was a big prison show. But it's really crazy when you get the letter that says, 'So, I'm getting out in three months, I've only been in for 17 years and I'd really like to meet you.'

If you love someone when you're 20 and you carry that love with you until you're 90, it's not going to be the same dynamic.
