rofl - touche! Now I know what that button is for. I read the video transcript now and - in three words, ignorance is bliss. If you're concerned, (another 3 words) you've grown up.
It is interesting - when I started using Facebook I was already grown up. And when I stopped using it, I had no regrets about what I posted. I only regretted spending time getting to know to much about people I would have been better off, knowing less about ;-)
Game on, bro ;-)
