I think the way we celebrate depends on our cultural context and believes. For example, in my Country, Colombia, most people celebrate dancing, drinking beer or a special drinking made of anise called Aguardiente; and eating with friends and relatives all night until the sunrise :D Meanwhile, depending on the believes, like christians, they celebrate in families with friends eating with soft drinks. In general, colombians don't like to celebrate alone, we believe: more people, more fun. And music and dancing are so important in our culture. In my case, i prefer the first one ;)
