     There's a man in the habit of hitting me on the head with an umbrella. At first I couldn't stand it, now I'm

used to it. 

      I don't know his name. I know he's average in appearance, wears a gray suit, and has a common face. I

met him five years ago one hot morning when I was sitting on a tree-shaded bench in Palermo Park, reading

the paper. Suddenly I felt something touch my head. It was the very same man who now, as I'm writing,

keeps hitting me, mechanically (机械地) and impassively, with an umbrella. 

     On that occasion I turned around filled with anger. He just kept on hitting me. I asked him if he was crazy,

he didn't even seem to hear me. Then I threatened to call a policeman. Calmly, cool as a cucumber, he stuck

with his task. After a few moments of hesitation, and seeing that he was not about to change his attitude, I

stood up and hit him on the nose. The man fell down, but he immediately got back on his feet, obviously with

great effort, and without a word again began hitting me on the head with the umbrella. His nose was bleeding

and, at that moment, I felt sorry for him. I felt regret for having hit him so hard. After all, the man wasn't

exactly hitting me; he was merely tapping me lightly with his umbrella, not causing any pain at all. Of course,

those taps were extremely bothersome. As we all know, when a fly lands on your forehead, you don't feel any

pain; what you feel is annoyance. Well then, that umbrella was one huge fly that kept landing on my head time

after time. 

     Convinced that I was dealing with a madman, I tried to escape. But the man followed me, wordlessly

continuing to hit me. So I began to run (I should point out that not many people run as fast as I do). He took

off after me, trying to land a blow. The man was out of breath so that I thought, if I continued to force him

to run at that speed, he would drop dead right then and there.
