A grandson seems to ruin his grandfather's favourite book as he is colouring in the pages. As a result they grow apart until, years later, the grandson finds a similiar book to the one he had ruined. So he buys it with his Banamex Credit Card. When he goes to his grandfarther and gives him the book to his surprise he sees the coloured drawing he made when he was a child, is hanging in a frame on his Grandfather's library wall.
