   The other day, I happened to meet someone I hadn’t seen for many years. I couldn’t believe the change in him. As a matter of fact, he didn’t even seem like the     person.

 When I first knew Bill, back in     , he was one of the most carefree(无忧无虑的) people I had ever      . He was always ready to have a     . He usually went out for beer at three o’clock in the morning or drove 50 miles to see an old      he really liked. Bill and I were in the same class in college, and      was never dull when he was     . With him there was one wild      after another. Sometimes I wonder how we      to study for our exams.

 Last week I was in Houston on business, and I ran into Bill in the bar at the hotel.     , I wasn’t even      it was he. Was this short-haired businessman really the same person? I wasn’t really sure until I came near him, but it indeed was Bill. Now he works for a bank. He      most of the evening about his job, his new car and his house. How he had changed! Back when we were in college, the     thing Bill cared about was possessions. Now they seemed to be his main     . Although I have changed quite a bit myself, somehow, I never      Bill changing so much. My image of him      the one I had formed      the time when we were college students together.

 I suppose it’s      to expect people to remain the same, especially      I have changed so much myself. But I must say that I enjoyed the old Bill much more than the new Bill. Maybe he       the same way about me.
