Biff Loman

 
" Will you take that phony dream and burn it before something happens?" Pg 106

I think from this quote, we can see that Biff know what might be going on. He wants to warn his father, but the way it came out is mouth sounded harsh. The tone of this quote also sound desperate to me. We can deduce that deep inside he cares about his father and he wants him to be good. Since he already know that something is going to happen, we can tell that he is a very sensitive person. He realise the sign of something bad is going to happnen.
