A daughter couple worried about Toshiyo's mother-in-law who had been blocked by loneliness after her father-in-law died. So, every weekend, I invited my mother-in-law to go out with three people, and Toshiyo gradually regained her energy. One day, Toshiyo was unable to come in a hurry because of his work, and had to spend the day alone with his son-in-law. It was supposed to be a fun day as usual, but my son-in-law began to say, "Mother-in-law, you're tired. I'll massage you."
