November 1st is El Dia de los Muertos — the Day of the Dead. Its origins can be traced to pre-colonial Mexico, when it was believed that the souls of dead loved ones returned to their families once a year so that their lives could be celebrated. Today, families mark the day by creating altars; some visit cemeteries to talk to their dearly departed. If you could talk to one person who has passed on...who would it be? A family member? A historic figure? And of course tell us why.
