WHEN it was becoming unbearable – once toward evening in November – and I ran along the narrow strip of carpet in my room as on a racetrack, shrank from the sight of the lit-up street, then turning to the interior of the room found a new goal in the depths of the looking glass and screamed aloud, to hear only my own scream which met no answer nor anything that could draw its force away, so that it rose up without check and could not stop even when it ceased being audible, the door in the wall opened toward me, how swiftly, because swiftness was needed and even the cart horses down below on the paving stones were rising in the air like horses driven wild in a battle, their throats bare to the enemy.
