About Langston Hughes, American poet, in her first book for children, she says, 'After my first meeting with Langston Hughes I promised I would write a book about him for children someday. Why? Because I, at 22, knew next to nothing of his work, and he didn't scold me he just gave me a pile of his books. And he was kind to me I will always be grateful that in his absolute warmth and generosity he fulfilled my deepest dream of what a poet should be. ' 'To me he is not dead at all. Hardly a day goes by that I don't think of him or speak of him. Once, just before he died, when he was sick with the flu, I took him a sack full of oranges. The joy I felt in giving that simple gift is never decreased by time. He said he like oranges, too.' What is the main topic of the passage?
