Overnight, as it were, he is a different man. He becomes a religious enthusiast. He is unable to focus on anything else. As soon as his sobriety begins to be taken as a matter of course, the family may look at their strange new dad with apprehension, then with irritation. There is talk about spiritual matters morning, noon and night. He may demand that the family find God in a hurry, or exhibit amazing indifference to them and say he is above worldly considerations. He may tell mother, who has been religious all her life, that she doesn't know what it's all about, and that she had better get his brand of spirituality while there is yet time.
