WALTER
You ain’t looked at it and you don’t aim to have to speak on that again? You ain’t even looked at it and you have decided – (Crumpling his papers) Well, you tell that to my boy tonight when you put him to sleep on the living-room couch…(Turning to MAMA and speaking directly to her) Yeah – and tell it to my wife, Mama, tomorrow when she has to go out of here to look after somebody else’s kids. And tell it to me, Mama, every time we need a new pair of curtains and I have to watch you go out and work in somebody’s kitchen. Yeah, you tell me then! (1.2.191)

Quote 27
WALTER
A job. (Looks at her) Mama, a job? I open and close car doors all day long. I drive a man around in his limousine and I say, "yes, sir; no, sir; very good, sir; shall I take the Drive, sir?" Mama, that ain’t no kind of job…that ain’t nothing at all. (Very quietly) Mama, I don’t know if I can make you understand. (1.2.224)
