Many cultures have celebrations that commemorate their ancestors.
Mexico's celebration, los Dias de Muertos, the Days of the Dead can be like a carnival, Young people throng the streets dressed up in ghoulish costumes. This is also a time for families to reunite in remembrance of those who have died. People go to market to buy what is needed for the ofrenda, or offering to the souls of the departed - special foods and other favorite items. The next morning everyone goes to the cemetery to visit the graves of loved ones who have died. They bring hoes to clear away weeds, and flowers to plant.
