When my father was getting ready for work, our house was ruled by knocks and words．He used to come downstairs to breakfast．The morning paper lay beside his plate．He always read the “Deaths” first, and then he knocked once on the table．One of my sisters brought his bread, already buttered for him．Usually he said nothing, but once I heard him say, “I love you very much, Edith．I would love more if you buttered my bread on both sides．” He read the paper all through breakfast．Two knocks on the table meant “I am ready for my tea．” If a single knock followed that meant, “More bread, please．”

After breakfast he said, “Boots．” The paper was spread（展开） for him over the back of an arm-chair．Yesterday’s paper was put on the chair for his feet, and his boots were brought to him, freshly cleaned．He read standing at the same time putting on his boots．With one boot finished he said, “Bus．” At that point one of the girls went outside to the garden gate and waited there．Her job was to stop a bus when it came．It came early sometimes and it had to wait for my father．“Overcoat, hat．” One of my sisters had already brushed his overcoat．Now she held it open for him．Another girl came with his hat, nicely brushed．“Handkerchief, pipe（烟斗）．” They were brought and put, with his tobacco（烟草）, into his pocket．He looked out of the window and said either “Walking stick” or “Umbrella”．It was handed to him．Ready now, he was still reading the paper．He didn’t put it down until he heard the shout “Bus coming!” Then he kissed my mother and went out．The girls breathed freely．
