There are five children in my daughter's swim class. On the first day, when there were only three children, the instructor really impressed me with his thoughtful, individual attention and judicious, appropriate use of each of the children's names. On the second day a new boy, Lewis, joined the group and I began to hear his name and the other boy's name, but the two girls had suddenly become "the girls". On the third day, a third boy, Kevin, joined the class. This not only solidified the girls' collective appellation of "the girls", but I began to hear "Kevin", "the boys", and "the girls". Does this instructor's ability to differentiate names stop at the number 3? Is 4 his " crow busting " number? Shoud I be concerned that he is in charge of the safety and well-being of my quiet, nascent swimmer? The instructor's name? I think it's...The Professor.
