This play features many personal changes in the Younger family as each of them go through experiences and face difficulties that make them very different from the people the audience are introduced to at the beginning of the play. Perhaps the biggest change is in the character of Walter. At the beginning of the play, he is depicted as an incredibly frustrated man with his situation in life and his lack of opportunities. He says to Ruth:
I'm thirty-five years old; I been married eleven years and I got a boy who sleeps in the living room--(Very, very quietly)--and all I got to give him is stories about how rich white people live.
It is his inability to get ahead in life that makes him so frustrated and feel so inadequate. Although at the end he has not had a reversal of fortunes, he has crucially been given the opportunity to show himself to be a man, thanks to the authority that Mama has given him. The way he faces Mr. Lindner and refuses his money bestows upon him massive dignity that shows the extent of the personal change he has undergone. Therefore, although all the main characters experience personal change, it is Walter who experiences the most significant personal change in this play.
