Gregor slowly pushed his way over to the door with the chair. Once
there he let go of it and threw himself onto the door, holding
himself upright against it using the adhesive on the tips of his
legs. He rested there a little while to recover from the effort
involved and then set himself to the task of turning the key in the
lock with his mouth. He seemed, unfortunately, to have no proper
teeth - how was he, then, to grasp the key? - but the lack of teeth
was, of course, made up for with a very strong jaw; using the jaw,
he really was able to start the key turning, ignoring the fact that
he must have been causing some kind of damage as a brown fluid came
from his mouth, flowed over the key and dripped onto the floor.
"Listen", said the chief clerk in the next room, "he's turning the
key." Gregor was greatly encouraged by this; but they all should
have been calling to him, his father and his mother too: "Well done,
Gregor", they should have cried, "keep at it, keep hold of the
lock!" And with the idea that they were all excitedly following his
efforts, he bit on the key with all his strength, paying no
attention to the pain he was causing himself. As the key turned
round he turned around the lock with it, only holding himself
upright with his mouth, and hung onto the key or pushed it down
again with the whole weight of his body as needed. The clear sound
of the lock as it snapped back was Gregor's sign that he could break
his concentration, and as he regained his breath he said to himself:
"So, I didn't need the locksmith after all". Then he lay his head on
the handle of the door to open it completely.
