Even after a year of living with my father-in-law, his back pain continues to worsen day by day. My wife asked him to let her wash his body since he's become hesitant to bathe alone, but he had no choice but to refuse. Lately, however, I can clearly sense a change in the relationship between my wife and my father-in-law. It's as if something new is beginning to stir between them. There's no way they could be bathing together... That's impossible. And yet, I can't shake the feeling that something unusual is going on.
