The family is our first culture, and, like all cultures, it wants to make known its norms and mores. It does so through daily life, but it also does so through family stories which underscore, in a way invariably clear to its members, the essentials, like the unspoken and unadmitted family policy on marriage or illness. Or suicide. Or who the family saints and sinners are, or how much anger can be expressed and by whom.
