Adolescence has been recognised as a stage of human development since medieval times--long, long before the industrial revolution--and, as it is now, has long been seen as a phase which centers on the fusion of sexual and social maturity. Indeed, adolescence as a concept has as long a history as that of puberty, which is sometimes considered more concrete, and hence much easier to name and to recognize.

Adolescents, for all their self-involvement, are emerging from the self-centeredness of childhood. Their perception of other people has more depth. They are better equipped at appreciating others' reasons for action, or the basis of others' emotions. But this maturity functions in a piecemeal fashion. They show more understanding of their friends, but not of their teachers.

Parents are never forgiven for not giving just the right response at the appropriate moment. Or, rather, there are particular times in the adolescent's or young adult's life, when a certain response is needed, and this need is not met, and the failure to meet this need is forever remembered, and is never forgiven.

The family is constantly changing, as each member changes. Some changes we recognize as developments, and the pleasure they bringusually makes us more adaptable. Some changes threaten, or disappoint other members, who may try to resist the change, or punish someone for changing.

Adolescents swing from euphoric self-confidence and a kind of narcissistic strength in which they feel invulnerable and even immortal, to despair, self-emptiness, self-deprecation. At the same time they seem to see an emerging self that is unique and wonderful, they suffer an intense envy which tears narcissism into shreds, and makes other people's qualities hit them like an attack of lasers.

We may be aware of small increments of getting older; we may meet an increasing number of people who make us uneasy with their youth; but the fact of being old ourselves comes as a surprise, and is often accompanied by the belief that there has been some mistake.
