Imagine John, into music and sports who marries Mary who enjoys the same things. Then John gets into some cult where he becomes someone else. Mary never married that John.
Mary was a lively woman who suddenly becomes an old lady over night. She doesn’t want to go out, listen to music, she wants to stay home and knit. John never married that Mary.
