Since my mother passed away five years ago, my father has been living alone at my parents' house. However, he is getting older and it's getting harder to take care of him, so since the beginning of this year, my wife has been coming to my parents' house during the day to look after my father, when she has free time from her part-time job. I was very grateful for my wife's kind nature, but one afternoon, when I happened to stop by my parents' house to check on her, I saw my wife being pushed by my father on the veranda...!
