I found myself facing a dry-cleaning store which had once been one of the best restaurants in New York. On Sundays the old man would take my mother and me for dinner. There had been a balcony（走廊）where a baker （面包师）in a tall white hat baked fresh bread ， and been whenever a customer entered， the baker would look down and put in a fresh batch（一炉）。I could see the manager who always sat down with us while we ate .He had some disease ， I suppose， because the right side of his face was swollen （肿的）out like a balloon ， but he always wore a hard wing collar and a white tie ， and never seemed sick .A Negro with a moustache was looking through the store window at me .For a moment I was anxious to go and tell him what I remembered. I did not go into the store ， nor even toward our house ， I went down town instead and sat in my room ， trying to read. What did the writer do when he walked away from the dry-cleaning store？
A．He stopped thinking about his childhood. B．He went to the field where the children were playing. C．He went into the restaurant . D．He returned to the room where he was staying.
