What's your biggest regret?

In high school, I kissed a guy who wasn't my boyfriend. I never really had a shot with the guy, but he wrote me some great, very romantic emails. Like letters [1], you could say. And my boyfriend at the time made me delete all of them.

That was seven years ago and I still wish I had them. And even though it's probably wrong, I think erasing those emails forever from my AOL account is one of my biggest regrets.

Folk singer Chris Blake also a little wistful, so he Googled "my biggest regret" and posted what he found inside a music video.:

Not surprisingly, people regret all kinds of actions and inactions and when it comes to love, the answers run from bittersweet to saucy:"Not going to college single [2]."
"Leaving the Webcam on."
"Getting married [3] so young and not finishing college."
"Not grabbing the most gorgeous girl I've seen in my life when I had the perfect opportunity."
"Not leaving [4] sooner."
"Not sleeping with that gymnast that had the hots for me."
"Sleeping with my girlfriend's mother."
"Going out with all the psychos."

Yeah, I wish I hadn't done that last one, either.
