For those heeding Gov. Andrew Cuomo’s stay-at-home order for the past month, windows have served as the only conduit to the outside world — and a little fresh air.

Those stuck inside lean out to make a phone call or smoke a cigarette. Some camp out on fire escapes to catch a few rays of sun, while others crane their necks to watch the intrepid few trudging along silent streets.

And, in a kind of voyeurism of the everyday, New Yorkers watch each other performing the mundane rituals of life in lockdown. Neighbors, who once might not have muttered a greeting, now eye one another, framed in the fluorescent glow of their living rooms, watching TV, playing on the computer or just pacing, waiting for the pandemic to end.
