What sort woman does George say he wants Beneatha to be?

George says he wants Beneatha to be a nice, simple, sophisticated girl.

I know it and I don't mind it sometimes ... I want you to cut it out, see—The moody stuff, I mean. I don't like it. You're a nice-looking girl... all over. That's all you need, honey, forget the atmosphere. Guys aren't going to go for the atmosphere—they're going to go for what they see. Be glad for that. Drop the Garbo routine. It doesn't go with you. As for myself, I want a nice—(groping)—simple (thoughtfully)—sophisticated girl... not a poet—O.K.?
