And he was kind to me; I will always be thankful that in his warmth he fulfilled my deepest dream (and need) 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 basket full or oranges. The joy I felt in giving that simple gift is undiminished by time. He said he liked oranges, too. "
