Keep 'em simple, clean, and preferably PG. They don't have to be deep, dark secrets that possibly involve the police and / or law enforcement. They can be as simple as "I'm lactose intolerant but I can't live without cheese!!" or "I managed to graduate without reading ANY prescribed texts in English!" or even "I hate action films. People think I like them, but I don't." But there's nothing stopping you from writing more serious confessions. We'll still love you. If you like, put your serious ones in a spoiler tag if you think they're going to cause problems to other users (possible triggers etc.) Confession: I didn't write the paragraphs above.
