They (= two other rumours) are that letters and documents sent to me are withheld by my secretaries lest they trouble me, and that my secretaries and colleagues prevent people who wish to see me from doing so. But I myself open and read all that is addressed to me at home. My mail, however, is so large that I cannot reply to everything, though I indicate to my secretary what I wish said and read the replies drafted by my secretary before they are sent.
