Of course, any theory needs example to prove its accuracy. The short story Mrs. Flowers, an excerpt from I know why the Caged Bird Sings by Maya Angelou, makes a great example. In the story Marguerite, A young black girl in the days when most blacks didnt have extra money for books, still striving for civil rights, was thrown a lifeline. Marguerite had deep emotional scars and didnt like to talk, nut loved to read. Mrs. Flowers had lots of books for Marguerite to read and help her to talk.
The story Raymonds run is also a good example. A girl named Squeaky, Raymonds younger sister, is charged with taking care of Raymond throughout the day. Raymond has a mental problem and needs looking after. When Raymond is with Squeaky she keeps Raymond on the inside of the street for his safety. Although Raymond might not always be aware he is leaning on Squeaky.
In both selections one character is helped by another. When in need someone is there to lean on. When they couldnt do it themselves somebody helped them. In one someone has mental issues, in the other a girl has emotional problems in both selection the point that we all need somebody to lean on is proven. At some point in life all of us will have problems and someone can help us
