Alice Munro, Canadian author and winner of the Nobel Prize for Literature in 2013, has written a number of short stories. Her short story, “The Bear Came over the Mountain”, circles around an old couple, Grant and Fiona. The story tells of an evolution of love under the background of aging. The love and aging interweave and collide with each other to generate the great theme of the story—love evolves with time and it will finally defeat aging. This paper attempts to analyze the components and structure of love at different stages and illustrate how love evolves in time and how it survives the battle against aging.
