Who am I?

Christmas is in winter here. I am in the continent of Europe. In my country, we honour the cow at Christmas because it is thought that when Mary gave birth to Jesus the cow in the stable breathed on baby Jesus to keep him warm. On Christmas eve, as the stars come out, tiny oil lamps are lit in every house, and after, midnight mass and Christmas dinner, streets fill with dancers and onlookers. People eat fried cod in barbeque sauce, roast goat and other food. People go to church, exchange presents and play on swing sets set up especially for the occasion.
