Airports also provide an unprecedented arena for people watching. I see single moms, trying to comfort uncomfortable children. Children screaming, wailing, wanting to be anywhere but in an airport. I see couples, about to be separated, exchanging hugs, tender embraces, kisses, sweet nothings. I see business travelers purposely striding to their gates, anxious to leave their business city and return back to their home. I see vacationers, relishing the last moments of freedom before returning to the mundane existence of day to day life. But best of all, I see.
