"I'm going to go back to doing just what I did before, the boy thought. Even though the sheep didn't teach me to speak Arabic. But the sheep had taught him something even more important: that there was a language in the world that everyone understood, a language the boy had used throughout the time that he was trying to improve things at the shop. It was the language of enthusiasm, of things accomplished with love and purpose, and as part of a search for something believed in and desired. Tangier was no longer a strange city, and he felt that, just as he had conquered this place, he could conquer the world."
