I was in lodgings (寄宿处) now, on my own, but the other lodgers had constant visitors up and down the stairs past my door. None of this disturbed me except one girl who sang softly to herself an old Russian folk song as she ran up to the room above. It was a sound of sweetness, musical, soft, unselfconscious and happy. I began to listen out for it, jumped up from my table, and threw open the door to catch a glimpse(一瞥) of her as she passed, but I was always too late. I asked the people upstairs who she was, and described the beautiful sounds she made. They became rather reserved(拘谨) and exchanged glances and hurriedly admitted it might be Sally. I thought she was someone special, not to be discussed in the ordinary way, and became a little curious to meet her. But the last thing I wanted at that stage was to get caught up with anybody. I’d just come to the end of a rather painful friendship, and now I had work to do.

One day, I came face to face with a girl on the landing. It was certainly her; whoever made that noise would look as she did. We stood and stared at each other too long for comfort. I broke the moment and, excusing myself, moved past her because it was too like the movies. I thought for some time of that long, silent stare, and laughed. She was tall and looked proud, with a slight , round-shouldered look that made me breathless and I didn’t know why.
