Oh Great Lord! I am writing this letter as my last confession, because I've sinned, I've failed you and I've desecrated your home, your name and my vestment; and that's why I am taking off my robe and dropping my vows, because I have to hide myself in order to not be sent to prison; I know you'll be able forgive me for what I did, because your love is infinite and I hope that someday those little man I've made so wrong, could be able to forgive me too and to get over any physical or psychological trauma I might have caused them.
The end.
PS: I've burned the confessional down, I had to erase any kind of proof I might have left.
