Kafka's A hunger artist ends with the description of a panther put in a cage in substitute of the hunger artist. The author says that each and every muscle and movement of the beast was proclaiming the freedom it enjoyed. "The food he (the panther) liked was brought to him without hesitation by the attendants; he seemed not even to miss his freedom; his noble body, furnished almost to the bursting point with all that it needed, seemed to carry freedom around with it too; somewhere in his jaws it seemed to lurk; and the joy of life streamed with such ardent passion from his throat that for the onlookers it was not easy to stand the shock of it." A similar description of such an action is seen in Metamorphosis when the Samsas were moving to a new apartment. "And it was something of a confirmation of their (the family members') new dreams and good intentions when at the end of their journey their daughter got up first and stretched her young body."
Observing the freedom enjoyed by stretching muscles I feel the same.
