What are some examples of other types of fences in the play?
I have so far come up with the gates of heaven that gabe dicusses on numerous ocassions, and the fence that must have surrounded the prison. I imagine that there is a reason the play is named FENCES and not The fence
There are various physical fences in this play, but there are also metaphorical fences. The physical fences include the fence that Rose wants Troy to put up around their house. Though this is a literal fence, it still stands for something more. Rose wants to keep her family in. She wants to build a fence around them to protect them and keep them together.
Troy's personal fences act more as a barrier to keep people out. He pushes his wife away by having an affair with Alberta. He pushes his son away by forcing him to quit football and focus on working instead.
Fences in baseball are also referenced. Baseball is a common theme in the play, as Troy was too old to play when blacks started to be allowed, and he is still bitter about this. He references hitting it out of the fence, which is how he applies himself to most aspects of his life. He cares so much about being a provider for his family that there isn't enough left in him to love them.
The racism that is prevalent in the play is a fence between different social groups. They keep people apart and keep them from understanding each other.
The play uses actual fences to symbolize the various fences we use in a personal and societal level. Each person has his or her own personal fence which acts to either keep people close or keep them away, just as the characters in Fences have their fences that serve their various functions.
