One striking and cardinal fact never to be forgotten considering its each and every phenomenon and stage is that the experiences of adolescence are extremely transitory and very easily forgotten, so that they are often totally lost to the adult consciousness. Lancaster[11] observes that we are constantly told by adults past thirty that they never had this and that experience, and that those who have had them are abnormal; that they are far more rare than students of childhood assert, etc. He says, "Not a single young person with whom I have had free and open conversation has been free from serious thoughts of suicide," but these are forgotten later. A typical case of many I could gather is that of a lady, not yet in middle life, precise and carefully trained, who, on hearing a lecture on the typical phases of adolescence, declared that she must have been abnormal, for she knew nothing of any of these experiences. Her mother, however, produced her diary, and there she read for the first time since it was written, beginning in the January of her thirteenth year, a long series of resolutions which revealed a course of conduct that brought the color to her face, that she should have found it necessary to pledge not to swear, lie, etc., and which showed conclusively that she had passed through about all the phases described. These phenomena are sometimes very intense and may come late in life, but it is impossible to remember feelings and emotions with definiteness, and these now make up a large part of life. Hence we are prone to look with some incredulity upon the immediate records of the tragic emotions and experiences typical and normal at this time, because development has scored away their traces from the conscious soul. There is a wall around the town of Boyville, says White,[12] in substance, which is impenetrable when its gates have once shut upon youth. An adult may peer over the wall and try to ape the games inside, but finds it all a mockery and himself banished among the purblind grown-ups. The town of Boyville was old when Nineveh was a hamlet; it is ruled by ancient laws; has its own rulers and idols; and only the dim, unreal noises of the adult world about it have changed.
