Though permanently joined, the two sides of the coin never look out on the same world.
It's a little like the predicament in which men & women find themselves.

"Women do not really know as much about men as they think they do.
They have developed, over the centuries, considerable techniques of adapting to men,
but that is not the same as truly understanding them.
Women often labour under the delusion that life is really pretty easy for men,
at least when compared to their own lot,
and have no idea what a complicated struggle is really involved in the transition
from male childhood to real manhood.
They have no idea of the long and arduous road that must be travelled by the male child,
who MUST separate himself from the original, indispensable, nurturing mother
and venture forth into a way of experiencing himself that is not her way
and that he cannot learn from her, either by example or instruction.
Considered in these terms, it is easy to see that a girl must learn to be like her mother,
while a boy must learn to be different from her
without this difference deteriorating into either antagonism or fear."

HE: Understanding Masculine Psychology
by Robert A. Johnson

"There's evidence that some women are now functioning very much like men,
doing what men do, seeking the same kind of short-term goals that men have
been taught to seek.
There is also evidence that discussions go differently when there are women
involved, that there is a change in tone and attention....
We talk now about the conflict that women have between work and the home,
and how terrible it is to be torn between two directions.
But women have always been torn.
We forget that when a women whose been married for a period of time gives
birth to a baby, she has to serve two masters.
She has to respond to two different kinds of needs.....
That is what it is to be a woman.
And this is what it is to keep a household going, to have multiple skills,
to deal with transitions,  to deal with the health of the whole.
There is a sense in which women have retained the capacity to be generalists,
to live in an ecology in which there is more than one life, and you have to
balance them off....
You know what people say about women...that they are easily distracted,
and that success has to do with focusing on specific goals.
But what if the health of the world depends on the same kind of capacity
that allows you, while you're feeding one child, to see that the other child
is reaching up and about to pull a cooking pot of hot liquid on his head?
This capacity to see out of the corner of your eye, and care about the health,
not just of one child, but of 3 or 4 and a husband and other members of the
family....that is the beginning of the capacity to care about the health
of a multitude of nations, or an environment of many species."
Mary Catherine Bateson

"Young people are increasingly preoccupied with their capacity to love as well as
be loved......
Sexual relations.....come about less frequently from a desire on the part of the
boys to present trophies to their own male vanity than to secure themselves
against anxiety that they may not be truly and deeply loved, or capable of love.
Many men and women agree that when physical sex is part of a positive,
caring relationship, it 'sustains, supports and heals in the individual journey'."
