I understand it's common to have seniors repeat stories. My father does this. But now it's two phrases that he may say twenty times in a 10 minute conversation. It's either, "that's for darned sure" or "I'll be darned." Often times he randomly says it when it does not pertain to the conversation at all. He is 82 and in excellent health. His memory seems good for his age. I realize it is a small thing, but it can be a bit irritating as I can compare it to a three year old constantly asking why?
