My informant tells me that despite her ethnicity, she does definitely not associate herself as being culturally Mexican. It is telling then that despite these claims, the part that she associates with the most in this tradition are the Mexican foods and treats that her family indulges in. Clearly tamales, Mexican chocolate, and the special breads do not make their rounds frequently, but when they do they are welcomed with open arms and mouths.
It is also a tradition that celebrates the liminal moments – the moments of transition. They open the gifts together at midnight on Christmas Eve, the moment when it exactly becomes Christmas. They celebrate that together. I also think it is interesting that they have the child transitioning to adulthood as the one who distributes the presents. It is a form of initiation and celebration for that person who is growing up. He or she is the center of attention for that moment.
