In the jungles of Laos, people have a tradition for marriage.
Girls around the age of 13-16 would dress up in traditional garbs and
line up in a straight line. The boys would come from surrounding
villages in and stand in a second line. They would spend the day
playing catch with these girls and singing love songs to them.
If the girl was interested they would get married. If not she would
sing a particular song to turn them off.
