K. sagte nichts dazu, aber es war eigentlich nicht die Wärme, die ihm Unbehagen machte, es war vielmehr die dumpfe, das Atmen fast behindernde Luft, das Zimmer war wohl schon lange nicht gelüftet.
K. made no reply, but it was actually not the heat that made him uncomfortable but, much more, the stuffiness, the air that almost made it more difficult to breathe, the room had probably not been ventilated for a long time.
