We are lucky where we live. During the quarantine lockdown we continued to walk our dogs in our neighborhood. Masked, we doubled our mileage by crossing the street, weaving to avoid other dog walkers.
People should always be aware of their surroundings and COVID seems to have taught people to look out for others.
Months after quarantine an outdoor etiquette has taken hold, a hierarchy, of sorts: a single runner should be the first to move out of the way for a family of walkers. A family with middle-schoolers should cede the path to a family with young children. A family with young children should step aside for the elderly couple using walkers. A person walking one dog should move aside for a person walking multiple dogs.
These are common courtesies for uncommon times.
