A confused young man was in a difficult situation. He couldn't decide whether to marry Kathryn or Edith. Even though he tried as hard as he could, he was unable to make up his mind.
Not willing to give up either, he strung them along for far too long. This indecision continued until both young women got tired of the situation and left him for good.
Moral of the story: You can't have your Kate and Edith too.
