When Linda is left alone to herself by Willy’s grave, she cannot, at first, cry. However, when she says, “We’re free and clear” (139), she starts to sob deeply. Why?
I think for any reason a wife would cry. She loved Willy. It was ironic that in the end he didn't live to see that they were free and clear. Which is the case of most who work themselves into an early grave. They never live to reap the rewards of struggle and hard work. In so many ways they were the typical older couple.
Keep in mind, Linda was of the old school where a wife was to be seen and not heard. I think too she grew tired of being the peace maker between Willy and the family.
