Postcards and Secrets

What is a secret? Something that only a few people know and for some reason don't tell others, perhaps something that just one person know or feel. What happens to secrets? Well, there is always the temptation of telling secrets to another person. So, what if someone ask high school and college students to send him their secrets anonymously in a especially designed postcard? He receives hundreds of postcards telling him all kind of secrets. Then there are enough secrets to make a very special book: My Secret: A Postsecret Book.
