welcome and then kindly asked the other passengers to make more room for the woman and her child. On

seeing this, people began to talk. "You know this conductor used to be very rude. Now suddenly he has

changed his bad behavior," said a middle-aged man. 

     "Yes, he should be praised and we must write a letter to the company," said a second passenger. "That's

right," another lady said, "I wish a newspaper reporter were here so that more people could learn from this

conductor."
