Forgive me if this has already been done.
Is there any dark secret you'd like to get off your chest? Something in your past you're ashamed of?
They say confession is good for the soul. Given the fact that we all share a kind of anonymity here, consider this your confessional. ;-)
I'll bite the bullet first:
When I was in college, I got crazy drunk at a dorm party once, then wandered across campus and slashed the tires on my prof's car because he'd given me a failing grade on a paper that I felt sure was at least a solid C-minus. The only reason I didn't get caught was that the 2 security guards on duty were both back at the dorm party.
