" My mother was determined that I should be able to walk two miles. If you could walk two miles, she said, you could get to most places you needed to get to. Actually, this is a fallacy. The fact that you can, with great difficulty, and taking an unconscionably time about it, walk two miles, will not get you anywhere you need, or at any rate want, to go. There were times when a wheelchair would have added another dimension to my life, but that was a forbidden subject; and it was not until many, many years later, long after my father and I were alone, that I took the law into my own hands and bought one; and instantly, dazzled with the new freedom that it brought me, swept my father off to his old haunts on an Hellenic cruise.
