It was not altogether forgetfulness. Psmith was one of those people who like to carry through their operations entirely by themselves. Where there is only one in a secret, the secret is more liable to remain unrevealed. There was nothing, he thought, to be gained from telling Mike. He forgot what the consequences might be if he did not.

So Psmith kept his own counsel, with the result that Mike went over to school on the Monday morning in gym shoes.

Edmund, summoned from the hinterland of the house to give his opinion why only one of Mike's shoes was to be found, had no views on the subject. He seemed to look on it as one of these things which no fellow can understand.

"'Ere's one of 'em, Mr. Jackson," he said, as if he hoped that Mike might be satisfied with a compromise.

"One? What's the good of that, Edmund, you chump? I can't go over to school in one shoe."

Edmund turned this over in his mind, and then said, "No, sir," as much as to say, "I may have lost a shoe, but, thank goodness, I can still understand sound reasoning."

"Well, what am I to do? Where is the other shoe?"

"Don't know, Mr. Jackson," replied Edmund to both questions.

"Well, I mean ... Oh, dash it, there's the bell." And Mike sprinted off in the gym shoes he stood in.

It is only a deviation from those ordinary rules of school life, which one observes naturally and without thinking, that enables one to realize how strong public-school prejudices really are. At a school, for instance, where the regulations say that coats only of black or dark blue are to be worn, a boy who appears one day in even the most respectable and unostentatious brown finds himself looked on with a mixture of awe and repulsion, which would be excessive if he had sandbagged the headmaster. So in the case of shoes. School rules decree that a boy shall go to his form room in shoes. There is no real reason why, if the day is fine, he should not wear gym shoes, should he prefer them. But, if he does, the thing creates a perfect sensation. Boys say, "Great Scott, what have you got on?" Masters say, "Jones, what are you wearing on your feet?" In the few minutes which elapse between the assembling of the form for call-over and the arrival of the form master, some wag is sure either to stamp on the gym shoes, accompanying the act with some satirical remark, or else to pull one of them off, and inaugurate an impromptu game of football with it. There was once a boy who went to school one morning in elastic-sided boots.
