The elderly are so often left out of the conversation about when it's appropriate to curtail or cease driving altogether. How do I know? I'm preparing the case to deliver to my father-in-law and I'm certain this is simply the human tendency to avoid uncomfortable subjects. This tendency to avoid or to become autocratic about driving is only human and we can and will overcome our natures to be better people, sons and daughters. Take the time to do it right. Research, document and find a way to be respectful and understanding when you finally have this difficult conversation. Remember ... this was the person that pulled over in the middle of nowhere to change your dirty diapers, taught you how to drive and probably helped you buy your first car.
