Parents and children seldom act in concert; each child endeavours to appropriate the esteem or the fondness of the parents; and the parents, with yet less temptation, betray each other to their children.

Context

“An unpractised observer expects the love of parents and children to be constant and equal. But this kindness seldom continues beyond the years of infancy; in a short time the children become rivals to their parents. Benefits are allowed by reproaches, and gratitude debased by envy. “Parents and children seldom act in concert; each child endeavours to appropriate the esteem or the fondness of the parents; and the parents, with yet less temptation, betray each other to their children. Thus, some place their confidence in the father and some in the mother, and by degrees the house is filled with artifices and feuds. “The opinions of children and parents, of the young and the old, are naturally opposite, by the contrary effects of hope and despondency, of expectation and experience, without crime or folly on either side.” source
