In A Raisin in the Sun, what makes Walter suddenly change his mind about taking Mr. Lindner's money?
Walter realizes that his son is watching his every move. Even if Walter feels like a failure because he squandered his father's life insurance money, he realizes that he cannot set such a poor example in front of his son. If he does, then what hope is there for him to ever be his own boss or for his son to know when to stand up for himself or his family? He also recalls how hard his dad worked for the money and how he would have never let someone intimidate him in the way that Mr. Lindner and the white neighborhood has tried to "buy off" the Younger family. His thoughts of his father encourage him to stand up proudly and decline the offer.
