The story is told about Franz Kafka that the last time he visited Berlin, he chanced upon a little girl in a park awash in tears. When he inquired as to the reason for her distress, she sobbed that she had lost her doll. Compassionately, Kafka countered that not to be the case. The doll had merely gone on a trip and, in fact, Kafka met her as she was about to leave. He promised that if the little girl would return to the park the next day, he would bring her a letter from her doll. And so Kafka did for several weeks, arriving each morning at the park with a letter for his new friend.
As his tuberculosis worsened, Kafka decided to return to Prague where he would soon die at age 41, but not before buying the girl another doll. Along with the doll came a letter in which Kafka insisted that this was the doll that belonged to his friend. Admittedly, she looked different, but then on her long trip the doll had seen many remarkable sights and gone through many searing experiences. Life had changed her appearance.
