¿De qué color es tu sombra?

Agustin is a boy who lives in a very, very tall building. So tall that the top story nearly touches the clouds. He likes to get close to the window and from there, gaze for hours at the city and at the other children playing down below. But nobody ever invites him to play... And it's because Agustin is different from the other kids: in a city where everyone and everything has a black shadow, Agustin has a shadow that is as yellow as the sun. This peculiarity makes him sad and causes many problems for him. But one night, in the middle of an earthquake, he is able to demonstrate how special he is and how his unique trait makes him shine even more brightly, especially in the eyes of the other children.
