The Jungle book

Nor do I think that you will sit here any longer, lolling out your tongues as though you were somebodies, instead of dogs whom I drive out - thus! Go!" The fire was burning furiously at the end of the branch, and Mowgli struck right and left round the circle, and the wolves ran howling with the sparks burning their fur. At last there were only Akela, Bagheera, and perhaps ten wolves that had taken Mowgli's part. Then something began to hurt Mowgli inside him, as he had never been hurt in his life before, and he caught his breath and sobbed, and the tears ran down his face.

"What is it? What is it?" he said. "I do not wish to leave the jungle, and I do not know what this is. Am I dying, Bagheera?"

"No, Little Brother. That is only tears such as men use," said Bagheera. "Now I know you are a man, and a man's cub no longer. The jungle is shut indeed to you henceforward. Let them fall, Mowgli. They are only tears." So Mowgli sat and cried as though his heart would break; and he had never cried in all his life before.

"Now," he said, "I will go to men. But first I must say farewell to my mother." And he went to the cave where she lived with Father Wolf, and he cried on her coat, while the four cubs howled miserably.

"You will not forget me?" said Mowgli.
