Is it true that Nicholas answers all of his fan mail at least once?

At one time, he was able to answer all his fan mail, but due to the sheer volume of letters he receives, he is unable to do so at this time. To answer everyone's letter would impinge on the time he needs to write, and again, he hopes you understand his decision. He does, however, tour extensively, and does his best to sign all books brought to his events, but there are some bookstores with their own guidelines as to whether or not previously purchased copies will be signed. The best advice is to contact the bookstore in advance, to see how the event will be run.
