filial obligation

Explanation:

Affiliate obligation is the term that refers to the attitudes, jobs, and services that children should do to their parents, expecting nothing in return and not being able to deny. This concept states that because the parents of the children have taken care of them and raised them, it is the obligation of the children to provide care, services, tasks and whatever is available to them and capable of meeting their parents' needs. An example of this is the phrase: "My parents took care of me for 18 years; I really shouldn't complain about having to take care of them for a while when they are sick."
