"If something like tying a knot in the drawstring of a tracksuit causes so much angst when it goes wrong, why not just get Tracey or Christian to help you? Why put yourself through that frustration?"
This was reinforced by something my brother-in-law John said. He and my sister, his wife, had engaged in a truly heroic struggle to try to save her life, so he had all-too-first-hand experience of many things that Tracey and I were going through.
He was telling me of a chap who was nursing his father through an illness that produced similar physical problems to mine. People thought the son was being heartless by refusing to help his father do all sorts of things the son could have done in an instant. He made his father struggle through these tasks. Well, he refused to offer help he could easily have given, that is.
