Re: Is wife liable to taking care of her in-laws?
The way i see it.... an adult "child" is responsible for taking care of their elderly parents. When that child gets married it is the responsibility of both the husband and wife to take care of both set of parents.
When the couple has mutual love and respect for each other.....you naturally love what they love (ie their parents).....therefore you would want to take care of them out of love and not out of obligation.
The way you take care of them varies from person to person of course.
as far as siblings are concerned....if they are unmarried and living under their parents roof then there is no obligation for a woman to take care of them UNLESS the parents can not do so for some reason.
