The street was a blind alley. Winston halted, stood for several seconds wondering vaguely what to do, then turned round and began to retrace his steps. As he turned it occurred to him that the girl had only passed him three minutes ago and that by running he could probably catch up with her. He could keep on her track till they were in some quiet place, and then smash her skull in with a cobblestone. The piece of glass in his pocket would be heavy enough for the job. But he abandoned the idea immediately, because even the thought of making any physical effort was unbearable. He could not run, he could not strike a blow. Besides, she was young and lusty and would defend herself. He thought also of hurrying to the Community Centre and staying there till the place closed, so as to establish a partial alibi for the evening. But that too was impossible. A deadly lassitude had taken hold of him. All he wanted was to get home quickly and then sit down and be quiet.
