As boys without bonds to their fathers grow older and more desperate about their masculinity, they are in danger of forming gangs in which they strut their masculinity for one another, often overdo it, and sometimes turn to displays of fierce, macho bravado and even violence.

Parents can fail to cheer your successes as wildly as you expected, pointing out that you are sharing your Nobel Prize with a couple of other people, or that your Oscar was for supporting actress, not really for a starring role. More subtly, they can cheer your successes too wildly, forcing you into the awkward realization that your achievement of merely graduating or getting the promotion did not warrant the fireworks and brass band.

Bad marriages don't cause infidelity; infidelity causes bad marriages.

As a guy develops and practices his masculinity, he is accompanied by an invisible male chorus of all the other guys, who hiss orcheer as he attempts to approximate the masculine ideal, who push him to sacrifice more of his humanity for the sake of his masculinity, and who ridicule him when he holds back. The chorus is made up of all the guy's comrades and rivals, his buddies and bosses, his male ancestors and his male cultural heroes--and above all, his father, who may have been a real person in his life, or may have existed only as the myth of the man who got away.

Early on, girls begin to menstruate, which is dramatic but not obvious to their playmates. They grow taller and rounder, but underneath their makeup they are still recognizably themselves. For boys it is far more disorienting. Puberty comes later, sometimes much later, and its delay is humiliating. While the tall round girls are getting themselves up like grown women, the prepubertal boys, with their featureless, hairless bodies, are just dirty little kids who could pass for the children of the hypermature girls.

Love is not something people feel, but something people try to express no matter how they feel.

We become male automatically because of the Y chromosome and the little magic peanut, but if we are to become men we need the helpof other men--we need our fathers to model for us and then to anoint us, we need our buddies to share the coming-of-age rituals with us and to let us join the team of men, and we need myths of heroes to inspire us and to show us the way.
