As I drove down Brookside Blvd. on Friday, I saw again the couple whose quiet wait for a city bus has caught my attention.  This time, the man stood leaning against a street sign, smiling, gazing down at the woman.  She held no cell phone on that day, and looked at him with bright eyes and an open face.  I slowed my car to study them until the driver behind me grew impatient, tapping on his horn.  I accelerated into the curve of the road, leaving the two behind, waiting for their bus, changed and yet, the same.
