Happy People

I'm often wondering the streets in Little Tokyo going to work, running an errand, or picking up a quick lunch. Usually Japanese tourists, city workers, cops, service workers, and small business owners are scurrying around with blank expressions, and completely oblivious to the homeless person on the corner, and even my curious gaze. I love to observe, and almost always, everyones behavior is predictable. However, maybe about once a month somebody will catch my gaze and smile. So I wonder: is this just a happy person who's not caught up in life's daily monotony? Or are they acknowledging another observer in passing. What ever the reasons, their smile usually makes my day, like today.
