FOUR YEARS AGO WAS OUR LAST NORMAL WEEK, AND NOBODY KNEW IT. Well, some of us had an inkling. I took my seminar out to a bar on the Thursday before spring break, and told them it might be the last time we were all together in one place, which turned out to be true. And Helen and I rented an Airbnb downtown for the weekend for a little getaway. A week later everything was locked down. Fortunately, I had plenty of supplies, and toilet paper.
