The scene is a trope in many spy novels and movies. The undercover agent moves through a foreign city, she is nervous. She looks at each passerby, is that man an opposing agent? Is the old woman by the vegetable stand really selling potatoes or is she a watcher? That man with the newspaper, is he on the lookout for her? The couple with the dog, innocent pedestrians or counter-intelligence operatives?
Going for a walk in the age of COVID-19 feels a lot like that. Every person on the street is a potential carrier. That old man without a mask, what is wrong with him? That woman sneezing, are those allergies or is she symptomatic? That guy with the water bottle, is that a dry cough or did a swallow go down the wrong pipe.
This is my city, but it is foreign all the same.
