The Burrow- Franz Kafka

Also I am not permanently doomed to this free life, for I know that my term is measured, that I do not have to hunt here forever, and that, whenever I am weary of this life and wish to leave it, Someone, whose invitation I shall not be able to withstand, will, so to speak, summon me to him. And so I can pass my time here quite without care and with complete enjoyment, or rather I could, but I cannot.
