Budapest, February 6, 1925

Dear Professor,

Communication with you by letter has become such a need for me that I feel uncomfortable when I go all too long without personal news from you. The Rundbriefe are, first of all, much too infrequent, also to some extent official, and, above all, more matter-of-fact, so that they don't compensate me for the loss of the lines directed to me. In my easterly corner, I also feel scientifically and personally downright lonely. All that presses me no longer to wait until you have the time and the desire to write to me
