I grew up in a small town, but one of my first visits to a large city carries with it an enduring memory. A man, skinny and bedraggled, on a street corner, shouting obscenities into his hat. I was just a kid back then, and didn’t understand the tragedy that man represented. I was just perplexed. I learned, somehow, later, to be afraid of people like that — maybe the reaction of the people around me that day informed that fear. Which is awful.
Yesterday, walking down the street in San Jose, there was another man standing on a corner shouting into the air, a stream of profanity. I just assumed he was on the phone.
