Reason could be that people get caught up in the excitement and enthusiasm of the moment, and don't think about the potential consequences of their actions.. people feel like they have to participate in the celebration in order to fit in or be accepted by Others. Some people may simply enjoy the feeling of being reckless which is not good. Drinking out of control. Whatever the reason, it's important to remember that celebrations should be fun and enjoyable for everyone involved, and should not lead to harm or damage in the place of Celebration.
