A dialogue between a policeman and student

Policeman: Excuse me. Stop. The light is red.

Student: I'm sorry. I did not notice.

P: Most of the people are in hurry.

S: If a man is in a hurry, he has to violate a signal.

P: The signals are for you people.

S: But sometimes, they are very long.

P: It depends. Laws are for everybody.

S: I don't agree. Laws are usually for the poor.

P: No one is rich or poor in the eyes of a law. It is equal to all.

S: But it usually does not happen. The poor are challenged and fined, not the rich.

P: You are mistaken. Throughout my service, I have treated equally.

S: Exceptions are there. You may do your duty honestly.

P: It is the same with everybody. If you are good, everyone is good.

S: It is not a general practice. I have different experience. If you do a good turn, you get a bad one.

P: No. Always keep in mind. Do well and have well.

S: It is an old saying now.

P: This is universal truth. It is ever green. It never becomes old.

S: O.K. If you say, I agree.

P: Thank you. One thing always keep in mind. Don't find fault with others. Always sweep before your own door.

S: Thanks for your advice. Good-bye.

P: Good-bye.
