This study was done to investigate the lives of the daughters- in- law caring for parents with dementia and participate in their lives through having quality time with them. Data were collected by depth interviews and interpreted through the hermeneutic circle as follows. These daughters-in-law have conflict between social custom and subjective self. They had ambivalence toward their demented partents-in- law and were fighting a battle between rationality and emotions in their mind. These daughters-in law and mothers-in- law did not get along and the parents' dementia aggravated the relationships. They were alienated from their family by the parents with dementia. The indifference of their family especially their husbands, made these subjects live in misery. They cared for the demented mother-in-law with hatred. Even though they had this yoke, there daughters- in-law were not able to throw off the shackles of convention.
