Only thing I can think of is a morning I was at Tacoma Mall. The food court had just opened and it was during a weekday that no one really shopped, plus it was 11 so it was pretty empty. I saw a dude just standing there, bored out of his mind at one of said restaurants. So, I impulsively walked up to the counter and went
"HI, YOU LOOK BORED."
He slowly nodded his head and smiled at me. xD And then I asked if I could hug him. So he walked around to give me a bear hug, then went back to work.
Nothing too great, I know. But for me, it's amazing and out of character because I've always been anti-social, introverted and shy. That one moment with that guy, just... I was totally different. >>; And I totally made his day!
