because my wife was hospitalized, my mother-in-law suddenly came to help from my wife's parents' house. my mother-in-law still efficiently does the housework, of course bathing, and even being my drinking companion, and even a little lower back massage as a filial piety... while watching my seemingly unguarded mother-in-law, i start to become aware of my mother-in-law. that night, perhaps because my wife wasn't there, i finally couldn't stand it anymore...
