This is meant to celebrate the child's life, in respect and appreciation for the parents. There is also dancing with colorful costumes, often with skull-shaped masks and devil masks in the plaza or garden of the town. At midnight on November 2, the people light candles and ride winged boats called "mariposas" (butterflies) to Janitzio, an island in the middle of the lake where there is a cemetery, to honor and celebrate the lives of the dead there. In contrast, the town of Ocotepec, north of Cuernavaca in the State of Morelos, opens its doors to visitors in exchange for "veladoras" (small wax candles) to show respect for the recently deceased. In return the visitors receive tamales and "atole". This is done only by the owners of the house where someone in the household has died in the previous year. Many people of the surrounding areas arrive early to eat for free and enjoy the elaborate altars set up to receive the visitors. In some parts of the country (especially the cities, where in recent years other customs have been displaced) children in costumes roam the streets, knocking on people's doors for a "calaverita", a small gift of candies or money; they also ask passersby for it. This relatively recent custom is similar to that of Halloween's trick-or-treating in the United States. Another peculiar tradition involving children is La Danza de los Viejitos (the dance of the old men) when boys and young men dressed like grandfathers crouch and jump in an energetic dance. In Belize, Day of the Dead is practiced by people of the Yucatec Maya ethnicity. The celebration is known as which means 'food for the souls' in their language. Altars are constructed and decorated with food, drinks, candies, and candles put on them. "Día de las Ñatitas" ("Day of the Skulls") is a festival celebrated in La Paz, Bolivia, on May 5. In pre-Columbian times indigenous Andeans had a tradition of sharing a day with the bones of their ancestors on the third year after burial. Today families keep only the skulls for such rituals. Traditionally, the skulls of family members are kept at home to watch over the family and protect them during the year. On November 9, the family crowns the skulls with fresh flowers, sometimes also dressing them in various garments, and making offerings of cigarettes, coca leaves, alcohol, and various other items in thanks for the year's protection.
