This is a common condition affecting large numbers of people in schools, colleges and workplaces. This disease is made widespread when a small number of people come back from a large festival and tell their friends how good it was. Their friends will then decide to go the next year and will purchase tickets. Other friends or colleagues will then want to go as they think this is starting to become a new trend and like to keep up with whats fashionable. Conflicts often occur when one group dislikes the thought of the other attending the event and arguments are common.
