Question: He lives in a separate house [away] from his parents, so is this inconsistent with fulfilling his complete duty towards them?
Response: No, it is not inconsistent with fulfilling his complete duty [towards them]; it is not necessary that he lives with his parents. However, he is required to serve them both and fulfill their needs and honour them – whether or not he lives with them.
