I am a person who doesn’t like waiting. I don’t like to wait in line, being put on hold when making a phone call, or arriving at an apartment to find that my companion will be         . And of course, I don’t like waiting rooms.
      , I realize that my agony(痛苦) will not be good for me, as an         crowded world can only mean one thing – more waiting.
       this, I have taken an action and decide to turn my frustration to productive ends. In short, I am looking for what I call “waiting-in-line”        .

On a recent visit to the general store, I placed my order at the         along with six or seven people. The old female employee seemed to have her hands full as she rushed        . “Young man, just be        ,” she said to me.
No problem. I quietly opened my dictionary prose(散文) and poetical quotations. Perhaps the other customers         me as a bookish, lonely soul. But         did they realize that I was enjoying the         of Shakespeare, Thoreau, Homer and Ben Johnson.
