"The title of A Raisin in the Sun is an allusion to Langston Hughes' poem "Harlem." In the poem, the speaker is asking what happens to a dream that is not realized. One of the images Hughes uses to convey the effects of this experience is that of a raisin drying and shriveling up in the sun."
The other discussion participant is very bland and open-ended with how she answers. She is not involved at all in the conversation and is just answering with simple answers to make it seem like she actually knows what she is talking about. This causes the conversation to be one-sided.
