Love will eventually return in another form.

 Franz Kafka, who was single and had no children, came across a small girl who was sobbing because she had misplaced her favourite doll when he was 40 years old and strolling through a park in Berlin. She and Kafka unsuccessfully looked for the doll.

The following day, she was to meet Kafka there, and they would return for it.

The doll was not to be found the following day, so Kafka handed the girl a letter "written" by it that begged her not to cry. I've travelled to see the world. I'll write to you and tell you about my travels.

This was the start of a tale that persisted right up until Kafka's death.

Kafka read the doll's meticulously written letters, which included experiences and discussions that the girl considered adorable, throughout the sessions.

Finally, Kafka handed her the doll that had returned to Berlin after he had purchased one.

It doesn't resemble my doll at all, the girl remarked.

Another letter from Kafka was sent to her, on which the doll had written, "My travels, have transformed me." The girl gave the new doll a big hug and brought it home smiling.

Kafka passed away a year later.

The adult girl discovered a small letter inside the doll several years later. It read as follows in the brief letter that Kafka signed:

Most likely, everything you love will be lost, yet love will ultimately return in another form.
