A few days ago, I walked into the pet store, and it felt different. Gone was the large plexiglass barrier that had separated customers and sales associates at the check-out counter. Was that a sign? Masks were still required, though the city's mask mandate was lifted. What’s safe and what’s not still seems a bit confusing. Covid-19 cases are down, yet the coronavirus is still infecting tens of thousands of Americans daily—including Barack Obama and Hillary Clinton—and the death rate is 1,300 or so a day, about what it was a year ago.
