<p>When I was a student, a professor was the top of the food chain. At my small LAC, if you were late to class, the door was locked and you were not admitted, but if he/she were late, we were to wait a minimum of 15 mins before assuming class was cancelled. I can’t imagine that if there were cell phones then, anyone would have dared to have it on. (my D hates these “back in the old days stories” but it is true!) Class '76</p>
