Dear Annie: My 58-year-old mother has a best friend whom she has known since they were 5 years old. We call her “Aunt Marsha.” She's been at all of our weddings and holidays. She is still friendly with her ex-daughter-in-law, who happens to be a good friend of mine.
In years past, when Aunt Marsha has a male companion in her life, she typically falls off the face of the Earth. Recently, she found a new guy who happens to be married, so her communication with us is limited.
