Once upon a time a big monk and a little monk were traveling together. They came to the bank of a river and found the bridge was damaged. They had to wade across the river. There was a pretty lady who was stuck at the damaged bridge and couldn't cross the river. The big monk offered to carry her across the river on his back. The lady accepted. The little monk was shocked by the move of the big monk. "How can big brother carry a lady when we are supposed to avoid all intimacy with females?" thought the little monk. But he kept quiet. The big monk carried the lady across the river and the small monk followed unhappily. When they crossed the river, the big monk let the lady down and they parted ways with her.
All along the way for several miles, the little monk was very unhappy with the act of the big monk. He was making up all kinds of accusations about big monk in his head. This got him madder and madder. But he still kept quiet. And the big monk had no inclination to explain his situation.
