Thepriest gives them special sweets, and the parents usually organize a party for their friends in their home. In Argentina, Mexico and several other Latin American countries, girls have a special birthday celebration when they reach the age of fifteen. After a special ceremony , the girls dance a waltz with their father and other boys.
