Agree, 樓主 should also help his mother 做家務. I have the experiende that I help several times for my mother in law to clean up dishes, however, his daughter never clean dishes and leave almost immediately after dinner. Then I have to give up lo. Why his daughter no need to tidy up? But we will have and paid for dimsum in restaurant with my parent in law everyweek.
You cannot expect others. But you have to do it first for your mother.
