My l4-year-old son, John, and I spotted the coat which was hanging at a secondhand clothing store in Northampton Mass. While the other coats drooped, this one looked as if it were   36  itself up. The coat had beautiful tailoring, a Fifth Avenue label and a(an)  37  price of $28, which was popular just then with   38  , but could cost several hundred dollars new. This coat was even better, bearing that   39  of classic elegance. John tried it on and the fit was perfect.
John   40  the coat to school the next day and came home wearing a big smile "Did the kids like your coat?" I asked. "They loved it," he said,   41  folding it over the back of a chair and smoothing it flat. Over the next few weeks, a   42  came over John. Agreement replaced contrariness and reasoned discussion replaced fierce   43 . He became more mannerly and   44 , eager to please. He would generously loan his younger brother his tapes and lecture him   45  his behavior.
When I mentioned this incident to his teacher and   46  what caused the changes, she said laughing. "It   47  be his coat!" Another teacher told him she was giving him a good   48  not only because he had earned   49  but because she liked his coat. At the library, we ran into a friend “Could this be John?" he asked surprisingly,   50  John's new height, assessing the cut of his coat and extending his hand, one gentleman to another.
John and I both know we should never   51  a person's clothes for the real person within them.   52  there is something to be said for wearing a standard of excellence for the world to see and for   53  what is on the inside to what is on the outside.
For John it is a time when it is as easy to try on different approaches to   54  as it is to try on a coat. The whole world, the whole future is stretched out ahead, a vast landscape   55  all the doors are open. And he could picture himself walking through those doors wearing his wonderful, magical coat.
