(Describe an unforgettable experience)叙述一个无法忘怀的经验

One day when I was a child, I saw an ad about a missing dog in the paper. As my next door neighbor had a German shepherd like the one described in the ad, I called the owner of the missing dog to tell him that. I also gave him my neighbor's telephone number.

I had almost forgot about the whole thing when I heard my neighbor talking in a loud voice one night. I rushed to the window immediately to see what was going on. "I am sorry, but this dog really belong to us. We have kept it for almost eight years now," my neighbor was explaining to a tall stranger.

Suddenly I felt rather guilty, for my childish suspicion of my neighbor seemed totally unjustified. But I didn't have the courage to tell him that it was I who had caused him all this trouble. I have been silent about this thing until now.
