Act two, scene one opens with Bono and Troy working on the fence. The fence is an extended metaphor in this play. (A metaphor that is continued over multiple sentences; a conceit) Both Bono and Troy have a hard time cutting the wood for the fence but, Cory joins them and has no trouble cutting the wood. I think Wilson is using this as symbolism to demonstrate the ability to handle adversity by the older generation and the newer generation. Also the topic of Rose’s desire to build the fence is brought up in conversation. Bono explains to both Cory and Troy that Rose wants the fence built to keep her family safe. So in this situation the fence represents protection. Bono also tries to talk to Troy “in code” about his affair in front of Cory. "Some people build fences to keep people out…and other people build fences to keep people in." This is a metaphor that while Rose is building the fence to protect her family; Troy is building a fence around his heart by shutting Rose out and having an affair with Alberta. Cory leaves to look for a saw and Bono confronts Troy about his affair more aggressively. Bono warns Troy that he should stop this affair before it is too late, foreshadowing the rising action. (Tension and conflict building in the story) But, we learn that it is already too late, when Troy blurts out a startling confession mid-argument with Rose. Troy uses analogy when telling Rose he is impregnated another woman, comparing it to stealing second in baseball terms. (Illustrates the ideas by linking the current idea to a more familiar idea to better communicate the idea at hand.) The argument becomes heated and Troy grabs Rose’s arm. Cory runs out of the house and punches Troy in the stomach. Troy seems quite comfortable using baseball analogies in serious situations. Troy walks off yelling, “Strike number two”.
