They probably have nothing doing in their life and need you to fill that void.
Don’t stop you normal household activities because of them. Learn to ignore those people. I have an in-law that likes to converse when I’m trying to eat, especially Shabbat lunch. At first I tried to be polite, but after a number of years, I feel taken for granted and disrespected. I now just ignore the person until I’ve eaten.
That same in-law does almost nothing for my kids, but thinks that coming over and providing (unsolicited and unwanted) advice is helpful.
In any event, some people are takers, and you have to put up a boundary.
