Just be polite, listen for a moment, then tell her you need to go. We called my next door neighbor Mr. Kravitz because he was just this way. His wife was the one that smoked, drank and golfed and he was the neighborhood gossip. It bothered me at first, but he was a really nice guy. He left for the hospital two weeks ago and may not come back. I wish I would have spent more time with him. He was just lonely.
