I remember being more excited to go to school on Fridays than any other day of the week. In elementary school, I followed a very conventional schedule: I went to school from 8:00 AM to 3:00 PM, Monday through Friday. Fridays were, of course, special. I think most people in the world have a soft spot for Fridays because they signal the start of the weekend—a glorious and triumphant day marking the end of a workweek. But that wasn’t my reason for loving Fridays.
