There is an old saying that all of us are born with two bags hung on our necks. A small bag in front of our chest is filled up with other people's faults（缺点）,while the big one at the back is full of our own shortcomings（短处）.
This makes it easy to find other people's faults, but hard to see our own faults behind us.
There was a boy named Tommy. He had four friends: Simon, Jack, Johnny and Harry. Tommy always opened the front bag to cheek what was in it. He saw other people's faults very quickly. When Simon was impatient with him, he said to Simon. It's so easy for you to get angry. It is hard to be friends with you."
Later that day, Tommy told his mother about Jack's dishonesty（不诚实）."Jack took my things without asking. He also forgot to return them." Tommy himself did not like sharing his things with anyone. When Johnny was too tired to play with him, he said, "You are such a rude（粗鲁的）person." He thought Harry was too proud of his rich parents. But Tommy was just proud of himself because he could not see any of his own shortcomings! He could not understand why he did not get on well with others. If only Tommy would tur the bags around, he would discover his own impatience, dishonesty, bad manners and vanity（虚荣）. They were no better than that of Simon, Jack, Johnny or Harry.
