What is the absolute dumbest thing you've EVER done in your life?

[Peter_20]

The dumbest thing I ever did was hesitating when the hottest girl in my ninth grade class told me that she wanted me. I regret it to this day, damn it.

And what's worse, I never seem to learn from my mistakes on this subject.
It sucks bigtime; whenever I have the chance, I miss it, and realize much later what I've missed.

I like to think of it as "The Curse of Peter", though - it makes the whole thing a bit more legendary and epic, and all that crap. XD

"Now God swore an oath to himself, an Oath of everlasting curse upon Peter the Hapless, an Oath which would follow him to the end of his life; an Oath, be it for the worse or the better, that should mislead Peter into darkness whenever he saw the girl of his dreams, a darkness which should turn him astray, and lose the girl of his desire."

Wow, that actually turned out pretty good. XD
