Happy Endings - Margret Atwood

A is a normal starting of the writing. A couple met and gets married, have kids, a good life and dies. This is the end of the story. I am not sure what the labeling of A B C and so on are for.
B shows a very different relationship between Mary and John. John is protrayed as a user and that he is not in love with Mary. This part of the story helps me to see many women. A lot of women think that a guy is in love with them, but in reality the guy is pleasing himself. Friends try to tell you better about the guy. In this kind of relationship women tend to believe that the guy is okay and the women can change then into what he can be. This is not true, people have to change themselves. Mary appears to be an insecure woman somewhat. Mary finds out he is seeing another woman. She takes her life for the love that she has for this man. John marries another woman named Madge. C Again, the relationship between John and Mary is being looked at in another angle. Mary is a younger woman having an affair with a married man, John. Mary is also in an affair with a guy who is in her age range,James. James is 22 years old and is not ready to settle down. I think I understand now, each Letter A B C and so on is a new ending!
John is married to Madge. They have two children and are very happy. Mary is experiencing excitement in the affair with John, the married man. John finds Mary and James in bed together. John later shots the two and himself. Madge marries Fred and continue to be happy.
Fred and Marge are at their home and a tidal wave almost drowns them. Fred dies from a bad heart. Madge devotes the rest of her life to charity work.

All of the endings had a somewhat happy ending considering. The final three paragraphs fit into the story by including all three characters and their endings.
