Sarindi And The Lucky Bird

Sarindi thinks that luck is like a mischievous monkey, playing hide-and-seek, and it seems to be hiding from Sarindi and his family. When Sarindi's father has an accident and loses his job as a becak driver, he says they must go to the bird market and buy a Lucky Bird. Then perhaps their luck will change. So does the magical song of the Lucky Bird change their luck? Does it change Sarindi's luck at marbles? Or do they make their own luck in the end?
