D
He looks like somebody important! I remember thinking about a middle-aged man standing at a checkout counter． Something set him apart． Even the boy bagging groceries seemed to sense it． He sped up than usual as he glanced with respect at the man．
Trying to find out what was different about him, I found that he looked quite ordinary． Although he gave the impression of being tall, I could see he was actually a little shorter than average． His appearance wasn’t particularly outstanding, and he was wearing plain weekend sports attire ( 运动休闲装 )． Not until the man was leaving did it strike me． He carried himself as if he were somebody worth caring about． Head up and chest out, he walked proudly from the market． I watched the other shoppers as they looked down over their baskets． And me? In the glass of the store’s side doors, I saw reflected ( 映现 ) a worn-out housewife who looked as if she’d carried too many bags of groceries．
Suddenly, the words I’d heard my mother repeat hundreds of times as I was growing up held new meaning． “Stand up straight ! Lift yourself by pretending strings are pulling you from the tops of your ears．” I thought of myself being pulled up ． I felt taller as I came nearer to the market’s doors． This time I saw reflected a woman who looked as if she knew where she was going! But as I rushed home in five o’clock traffic and tried to fix dinner before a seven o’clock meeting, my good manners disappeared． It wasn’t until the next day as I was trying on clothes in a department store that I remembered again． Each thing I put on seemed wrong． Suddenly I recalled the man in the supermarket． I lifted myself up． The dress looked nicer on me． I liked the dress! Sure enough, I looked five to seven pounds lighter． Dieting titles I’d read came to mind, such as “How to Lose Pounds in Weeks?” Now I had a new title: “How to Look Thinner in Seconds．”
