Masculinity varies from time to time and place to place. But it doesn't exist just in the mind of a single guy: it is shared withthe other guys. It is a code of conduct that requires men to maintain masculine postures and attitudes (however they are defined) at all times and in all places. Masculinity includes the symbols, uniforms, chants, and plays that make this the boys' team rather than the girls' team.

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

Parents vary in their sense of what would be suitable repayment for creating, sustaining, and tolerating you all those years, andwhat circumstances would be drastic enough for presenting the voucher. Obviously there is no repayment that would be sufficient . . . but the effort to call in the debt of life is too outrageous to be treated as anything other than a joke.

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.

Each generation's job is to question what parents accept on faith, to explore possibilities, and adapt the last generation's system of values for a new age.

Marriage, like a submarine, is only safe if you get all the way inside.

Character, not passion keeps marriages together long enough to do their work of raising children into mature, responsible, productive citizens.
