At the annual ceremony in December, all children under twelve are formally advanced into the subsequent year. At twelve, they receive their assignments in the community, which will dictate their place in society for the remainder of their life. Naming of new children takes place at this ceremony as well. When children become nines, they are given a bicycle. The bicycle symbolizes their growing independence from their family unit and their moving out into the community as individuals. It's a sign of maturity, and it shows the trust that the community now puts in them to have the kind of freedom that a bicycle can endow. It's not much of a secret that the children start to ride bikes before nine, but owning your own is an important step towards becoming a fully contributing member of society.
