What metaphors are used in The Belle of Amherst by William Luce?

Emily describes a little path between the to homes. She says that it was just wide enough for two lovers, but that she and Sue were the ones who most often used it. She uses the path as a metaphor for her relationship with Sue. She says that she loved Sue dearly, but that Sue didn't understand her love. Emily believes that the way she loves is dangerous and that bliss is unnatural. Therefore, when the path becomes overgrown from disuse, she simply says "it's best to abandon paths when you find they lead nowhere." This is a fitting description for her love of Sue.
