All her life, my mother wanted busy children. It was very important that her house should remain at all things 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 tables. 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 mon for one of us, upon returning from the bathroom, to find the 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.
