One of my indulgences is the darker sibling to Cute Overload: PostSecret.
People send in postcards with their secrets. Sometimes it's just the presentation of the secret that's delightful (like the sales clerk who managed to print up a sales receipt with the items being listed one after the other resulting in "I can't wait to quit my job."). Sometimes the secrets are dark and disturbing... and make me realize that I'm either extremely well adjusted or extremely boring. Or both.
What would your secret be to send in?
