Death of a Salesman

I think the characters have a lot in common. Willy wanted money and to be happy. Happy just did what his dad wanted him to do to make him happy. Biff just wanted his dad to be happy with him. In the end Biff ended up not caring anymore. He did what he wanted. Willy gave up, he ended his own life. Happy just went with the flow and he will not end up happy in the long run.
