It's a good and sometimes funny analogy - the only thing that I don't get is a reference to people " whose job it is to look after you". For adults (different story for children) that's yourself. So many people going through cancer have learned that critical bit of understanding - you (not someone else) are responsible for your decisions. You know best what treatment and side effects you are willing to go through for a possible cure - not your loved ones, not your children, not your spouse or even parents. No matter how much they may care for and need you. You are responsible for your own well being, and if that means sidelining people who cause you grief, even in your own family or former best friend, well off you go. If we are lucky, we have benefitted enormously from the love and support of others. It's a wonderful thing. But it's particularly wonderful because it is freely given, not an obligation or a duty.
