     My grandfather was a teacher, he was the headteacher of a school for boys between the ages of

thirteen and eighteen. I know that he was a kind and gentle(温柔的)man at heart, because when I was

young, he gave me presents, and sat me on his knees, and told me stories. But I believe the boys at his

school were afraid of him.

     At school, when he walked into a room full of noisy boys, there was silence at once. When he looked

at a boy with a certain look in his eyes, that boy went red in the face, and looked down at his shoes. If

a boy brought him poor, careless work, the work that was not the best that boy could do, my grandfather picked up the boy’s book and threw it across the room, shouting, “Do it all again, and bring it back first

thing in the morning!” If the boy was late, or if he forgot to bring the work, he had to do it again, and

again, and yet again. My grandfather never forgot. He was a very different man at school, from the man

I saw day by day in his own home.
