They went through the same old rite:
Once every second year all Massai boys (aged 13 - 18 years) go through circumcision. Without anaesthetic. Screaming or weeping they have to avoid, put him and his family to shame.
After that they have to stay alone for 4 weeks, far away from their village and family. Coming back, their fathers will give them some head of cattle. Now they are marriageable.
