It should see these things. Only, without comment. Let nothing be exaggeratedly hidden. By instinct, let us preserve the decent privacies. But if a child occasionally sees its parent nude, taking a bath, all the better. Or even sitting in the W. C. Exaggerated secrecy is bad. But indecent exposure is also very bad. But worst of all is dragging in the mental consciousness of these shadowy dynamic realities.
In the same way, to talk to a child about an adult is vile. Let adults keep their adult feelings and communications for people of their own age. But if a child sees its parents violently quarrel, all the better. There must be storms. And a child’s dynamic understanding is far deeper and more penetrating than our sophisticated interpretation. But never make a child a party to adult affairs. Never drag the child in.
