Capote was also very flamboyant in his demeanor and certain aspects of writing without being explicit in interviews and conversations; the notoriety of his book Other Rooms, Other Voices and its provocative photo of the author is one oft-cited example (PBS par. 3). He also enjoyed company alone with other men but didn't really discuss sexuality (Clarke). Writing allowed Capote an outlet for all of his personal secrets that his life insisted he keep. This was an outlet both early and late in the author's life, as he recalls beginning to write at the age of eleven as a substitute for making friends, and the author's last book (never published or even finished) was essentially full of the details of the lives of celebrities Capote knew (PBS par. 1, 6). He also liked being kept in the middle of excitement without needing to reveal himself,...

His description of extravagant tours around Europe are filled with details of others but reveal little of himself (Clarke & Inge). Even as he is able to release his inner thought through his writing, he is unable to reveal himself personally.
