I saw this somewhere and it gave me the idea to do it, because it seemed not only really neat but it also somehow brought a lot out of some people. It doesn't matter who you are, what the confession is...just do it. Don't be scared. No one will judge you here, this is here for you. I won't say a thing back to any confession unless asked to. I plan to comment it myself sometimes and confess a few things on my own.
