A raisin in the Sun is a play with idealistic color, which is in opposition to the worship of money in the society. In the script, the characters in this family all share the same selfishness and expectations as the people in real life. However, they also have pride for race and hope to be respected, self-sacrifice for the family and the growth of the children. The characters in the play have their personal life details, but also their faith in family, love and race. The script is different from the novel in that it has a lot of dialogue and some scenes. This is because the audience can get to know the information conveyed on the stage for the first time. In the first act, they appear in an old, crowded house. This is the information that the story attaches to the characters, indicating that they are not a wealthy family. Their morning dialogue also shows the connection between the characters. The dialogue seems plain, and it feels like an ordinary family should say it. However, this is all artistically done, and in reality, such dialogue is unlikely to occur. Because in reality, people tend to pay more attention to actions than words. Dialogue, however, is the most direct and accurate way in which the script is communicated to the audience. And the characters in the script are at the heart of the story. For example, Walter showed his stubbornness and selfishness in some things. He was looking forward to an opportunity when his family could look up to him. His dream was shattered by an accident. Then he had to sell the house to appease his family. So Walter here was selfish for a reason. He valued his family, but he also hoped that his family could depend on him. In the end, he did not sell the house, because in addition to his family he had pride and faith in his race. This is also the education he received and the education he gave to his children.
