To Mr. Reed who had previously answered my question on realism in A Raisin In the Sun and told me to to write about Travis sleeping on the couch , thank you but I need to write realism in Acts 1, 2, 3 and since you thought that only the second one was wrong and isn't realism , I chose this quote for realism in Act Two:

MAMA (The mother and son are left alone now and the mother waits a long time, considering deeply, before she speaks)
Son – you – you understand what I done, don’t you? (WALTER is silent and sullen) I – I just seen my family falling apart today… just falling to pieces in front of my eyes…We couldn’t of gone on like we was today. We was going backwards ‘stead of forwards – talking ‘bout killing babies and wishing each other was dead…When it gets like that in life – you just got to do something different, push on out and do something bigger… (She waits) I wish you say something, son…I wish you’d say how deep inside you you think I done the right thing

My explanation for why it is realism : Mama is an example of a someone who is pressured into taking action they wouldn't normally take because of other people to outside forces. Mama realizes that the harmful atmosphere is only hurting the inhabitants . Reacting to this chaotic and hostile lifestyle, mama uses her check to invest in a new hopefully promising home. She need to make a big decision in order to get her family back in track even if it meant disappointing her son, she feels that it's the best thing to do . I'm mean if everything seems to be falling apart, you would do anything to fix it . She took matters into her own hands. This is a talk between a mother and son, where the mother feels she needs to justify why she brought the house.

But does my explanation for this quote in act three explain why it is is realism?
MAMMA: There is always something left to love. And if you ain’t learned that, you ain’t learned nothing. (Looking at her) Have you cried for that boy today? I don’t mean for yourself and for the family ’cause we lost the money. I mean for him: what he been through and what it done to him. Child, when do you think is the time to love somebody the most? When they done good and made things easy for everybody? Well then, you ain’t through learning – because that ain’t the time at all. It’s when he’s at his lowest and can’t believe in hisself ’cause the world done whipped him so! When you starts measuring somebody, measure him right, child, measure him right. Make sure you done taken into account what hills and valleys he come through before he got to wherever he is.

My explanation : Even though Walter loses their money, Mama still tells Beneatha to love and support him. She criticizes beneatha for her lack of empathy and for placing her own concerns about her own dream before concerns about loss of Walters pride. She wants Beneatha to cry for Walter and everything he has been through ans try to understand how hard he has been trying to making everything better for his family. I feel like this is like a typical family relationship where the brother and sister argue and fight and the mother has to go and to try and fix it. Mama understands what Walter is going through but Beneatha does not and blames him for losing to money for her medical school.

You are right. How we interpret a play or any other work of art is highly individual. The only thing I can add, or suggest, is that Mama sees the world and her family as it is in her own eyes, realistically AS SHE SEES IT.

Your explanation for the quote in Act Three does provide a realistic aspect to the play. In this scene, Mama shows her unconditional love and support for Walter despite his failures. She emphasizes the importance of empathy and understanding, encouraging Beneatha to consider the hardships Walter has faced before judging him. This interaction showcases the dynamics of a typical family, where conflicts arise and the mother takes on the role of mediator. Mama's understanding and forgiveness towards Walter's mistakes add depth to the play's realism, highlighting the complexities of family relationships and the need for compassion even in difficult circumstances.
