Can a married daughter serve her parents if her brother neglects them?
A daughter's right and duty to serve parents
Sons and daughters are both parts of their parents, so if a son neglects them, a daughter should win over her in-laws and serve her parents. The right is hers too, though it is a hard situation.
Then it is the daughter's duty to bring her in-laws' side around and serve her own parents.
