The office where I spend my days looks out across a restaurant parking lot to a major intersection in the Maryland suburbs of Washington D.C. The restaurant draws people who work in offices like mine, mostly well dressed and prosperous appearing. There are groups of men, groups of women, couples, arranged meetings, and a few singles. I am on the ground floor, so I have a good view of this activity. I also have a good view of the activity just beyond it where Nicholson Lane crosses Rockville Pike. All day long the cars and trucks travel there: slowing, waiting, signaling, turning, sometimes honking. There are usually lines of cars just sitting and waiting their turns. This is why the intersection draws homeless people seeking assistance in the form of cash. Quite often there are several of them, and quite often they are there for most of the day. I have watched them in the cold of winter, the heat of summer, and everything in between.
