     All her life, my mother wanted busy children. It was very important that her house should remain it all

times clean and tidy.

     You could turn your back for a moment in my mother's house, leave a half-written letter on the dining

room table, a magazine open on the chair, and turn around to find that my mother had "put it back where

it belonged," as she explained.

     My wife, on one of her first visits to my mother's house, placed a packet of biscuits on an end table and

went to the kitchen to fetch a drink. When she returned, she found the packet had been removed. Confused

(疑惑的), she set down her drink and went back to the kitchen for more biscuits only to return to find that

her drink had disappeared. Up to then she had guessed that everyone in my family held onto their drinks, so

as not to make water rings on the end table. Now she knows better.

     These disappearances had a confusing effect on our family. We were all inclined to (有……的倾向)

forgetfulness, and it was common for one of us, upon returning from the bathroom, to find that every sign

of his work in progress had disappeared suddenly. "Do you remember what I was doing?" was a question

frequently asked, but rarely answered.

     Now my sister has developed a second-hand love of clean windows, and my brother does the cleaning

in his house, perhaps to avoid having to be the one to lift his feet. I try not to think about it too much, but

I have at this later time started to dust the furniture once a week.
