Both of these men feel trapped by society and the rules put upon them only because they are black men. The title of Troy's play, "Fences" gives this away...Troy is trapped and blocked on all sides by what he wants (his dream of baseball). Walter is also depicted by the title of his play--he is the raisin--dried up by the sun of society rather than allowing him to remain a fully intact and juicy grape, full of life and freedom. Walter's problem is coupled by his poor choices and trust in people who are not worthy of his trust. He is betrayed not only by society, but also by friends and family.
