So refreshing, to find politeness and consideration in girls of that age. Too often (I reflected, thinking of Sabrina) they display only thoughtless ingratitude. But thoughtless ingratitude is the armour of the young; without it, how would they ever get through life? The old wish the young well, but they wish them ill also: they would like to eat them up, and absorb their vitality, and remain immortal themselves. Without the protection of surliness and levity, all children would be crushed by the past – the past of others, loaded onto their shoulders. Selfishness is their saving grace.
