There is no indication of what the feud actually is in the play, the only thing that the reader actually knows is that is was something that lasted for a very long time. I was actually kind of let down when I realized that there is no information on why the two families were actually fighting.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
