My memories of high school physics came back to me. In the fourth grade, or perhaps even in the third grade, the teacher actually paid attention only to those who were really careful. He didn't care what the rest of the class did, he was in class for those who would be in physics. Maybe it's just my generalized view of the past, it is certain that I have kept this feeling of the clock in my memory to this day.
