To me, and I'm sure for other writers, too, characters come back and they relive again, but what about those characters who only live for a page or two? Or for five pages or 10 pages. I like to think they're still out there - still living - but for me they kind of die, too. It's kind of sad. I don't think about them anymore unless I give them life again.
I used to be surprised and a little annoyed when characters would reappear in my mind, itching to be in another story. Now I realize it's part of the deal, that you create these people out of thin air but then, if you do it right, they actually live.
My characters tend to be people who are looking back on a life lived, their joys, their regrets.
Lot of stories in deceit, how characters deceive other people, but most of all, I think, how they deceive themselves. We're not as tricky as we think we are.
I usually have a location and then I put the character there. I love place names. I think I'm tricking myself by being so specific - it suddenly becomes real to me. Just because I say it's Chicago, Illinois doesn't mean it's true, but place names sort of make me grounded and then I can put some people there.
