In our modern world we are surrounded by glass: that miracle hardened substance that allows us to look right through it. Behind a glass windshield we survey our neighborhood as we move silently along strapped safely within our automobile. Was that a tent I saw behind that bush? From behind an office tower’s tinted window we look down on the streets below seeing people walking and talking; sometimes we observe a person carrying a worn shopping bag or someone bearing an overstuffed knapsack. Or in front of a building we pause to stare at the glass screen of our smart phone. We now witness a breaking news story: city work crews clear a sidewalk homeless encampment. As we contemplate that unfolding but far-removed scene, a clean well-groomed homeless woman walks by us.
