The lady I see always seems like she's just a stone's throw away from the icy cold hand of death, so why the hell is her family letting her waste what little time she has left on the planet doing this meaningless task?! Some would say that it's what she does, what she always done...so what? Get her to stop. If there's an old lady in your family do this then do them a favor, take them out to see the world.
Take them to a museum so they can see their old friends. Go to a ball game and let them tell you about how they always wanted to sleep with Dimaggio (Who didn't?) Do something to fill their lives with something other then a damn stupid task like sweeping the sidewalk.
