A father asked me for advice. His wife had left him (a good husband, but authoritarian), and he had found a letter, written by their young son, which his son had not posted. Among other things, it said: "Oh mother I cannot live without you. I may die without you. My dear mother please." What to do? I gave the father four suggestions, and was surprised which one he followed: post the letter. OBSERVATION: Mother came home immediately. One of my basic principles when dealing with such problems is: does everyone understand the full picture? That is why this was among my suggestions.
