In Mexico, the día de muertos, or literally, "day of the dead", is a joyful annual celebration to honour the dead. It is believed that, on this day, the spirits of the dead return home to visit their families. Toys, decorations, and candies in the form of skeletons and skulls, reflecting the lighthearted attitude of Mexicans towards death, are sold in the market-places at this time every year.
