He is 22 years older than me and he is in his 80's. Does there come a time when I can no longer carry on a regular conversation with him. He is congnitive, and doesn't have anything but COPD. But, it just seems like he is trying to talk with me, but he is just not able to. It is hard to explain. He maybe is able to, just we are not on "the same page". It gets frustrating when I have to explain everything from my point of view, so he gets what we are really talking about. I guess that happens with anyone.
