" Like the pain of a bad wound, the effect of a deep shock takes some while to be felt. When a child is told, for the first time in his life, that a person he has known is dead, although he does not disbelieve it, he may well fail to comprehend it and later ask--perhaps more than once--where the dead person is and when he is coming back. "
