One day, when Xiao Ming was on his way home, he saw a bird singing in a tree. He was very glad. He thought if he caught it, he would take it home and put it in his cage. So he picked up a stone and threw it at the bird. The bird was badly hurt and fell off the tree. Just then an old man came up to Xiao Ming and told him not to kill birds again.
