It's October 31, the first of the Days of the Dead in Mexico, and Maria Molina and her family are in the graveyard to honor her baby brother Pablo, who died when he was just a few months old. A candle flickers in the dark night, and on Pablo's grave they have placed his favorite toys, some chocolate, a sugar skull, and even a small 'Bread of the Dead.'Throughout Mexico, other families are doing exactly the same thing, for the threeday festival of The Days of the Dead is one of Mexico's most important holidays.
