Peter knew that, when his father spoke so, he meant what he said. But the little boy thought he would not eat his crusts until he had to do so.
He said to himself, "In a week I will begin to eat them all up. But now I will still put them under my plate."
So, every day when his plate was taken away, there were the crusts. Peter did not see his father look at them. And his father said nothing more about them.
By and by Peter began to think that his father had forgotten.
So, when the week was over, he said to himself, "I am sure that my father has forgotten. I am going to keep on leaving my crusts."
But his father had not forgotten. He was just waiting to see if Peter would obey.
That noon he saw that Peter had left a crust.
He said, "My son, you have not learned to eat your crusts. And you have not learned to obey. I must teach you."
Then Peter was more naughty still. He said, "I do not like old crust. I will throw old crust away. Then I cannot eat it."
He picked up the crust and jumped down from his chair.
