It is not however, adulthood itself, but parenthood that forms the glass shroud of memory. For there is an interesting quirk in the memory of women. At 30, women see their adolescence quite clearly. At 30 a woman's adolescence remains a facet fitting into her current self.... At 40, however, memories of adolescence are blurred. Women of this age look much more to their earlier childhood for memories of themselves and of their mothers. This links up to her typical parenting phase.

The myth of independence from the mother is abandoned in mid- life as women learn new routes around the mother--both the mother without and the mother within. A mid-life daughter may reengage with a mother or put new controls on care and set limits to love. But whatever she does, her child's history is never finished.

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.

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.

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.

One of the main tasks of adolescence is to achieve an identity--not necessarily a knowledge of who we are, but a clarification ofthe range of what we might become, a set of self-references by which we can make sense of our responses, and justify our decisions and goals.
