I saw this video, and it reminded me of how hard it is to yield trust ... I think living in the big city has made me a little harder. I know myself well enough to know that if I saw this on the street, the first thing that'd cross my mind would be to suspect that it was a distraction technique for the sign-holder's accomplice to pick my pocket.
I sure do wish I didn't think like that, though. I see something like this, and it makes me wish that I were a little more of a risk-taker in terms of vulnerability. I realize my caution is pragmatic, but ... seeing something like this reminds you that the world still has the potential to be a nicer place.
