There once lived a boy named Woo Sing,   61 father brought home a mirror. Woo Sing had never seen one before so when he saw it for   62 first time, he didn’t understand   63 it was, but he saw      another boy in the mirror, which made him very happy, for he thought the boy had come to play with him. He spoke to the stranger in a very friendly way, but received no reply. He laughed and waved at the boy, who did   64 (exact) the same thing.
