    It was at an exhibition of the artist's woks organized by the Red Cross. I was invited as a special guest to attend the exhibition. During this period, two cute girls of 16 or 17 years old came to me and asked me for my signature(签名).

“I haven't bought my pen. Is the pencil okay?" Actually, I knew they wouldn't refuse. I just wanted to show a well-known writers good manners to the common readers.

“Certainly,” the young girls readily agreed. I could see they were very excited. Of course their excitement also made me feel more pleased and satisfied. One of the girls handed her fine notebook to me. I turned over the cover of the notebook, wrote a few words of encouragement naturally and signed my name. The girl read my signature, frowned(皱眉), looked at me carefully and asked. “Aren’t you Robert Char?”

“No” I told her proudly, “I'm the author of Alice Adams, the winner of two Pulitzer Prizes.”

The young girl turned to the other, shrugged (耸肩) and said, “Mary, lend your rubber to me.” At that moment, all my pride turned into a bubble(泡泡) immediately. Since then, I always warn myself: no matter how outstanding you are, don't think highly of yourself.
