Ubuntu = I am because we are.
Referring to: Justin Matthew via Google+
An anthropologist proposed a game to children in an African tribe. He put a basket full of fruit near a tree and told the children that whoever got there first won the sweet fruits.
When he told them to run, they all took each others hands and ran together, then sat together enjoying their treats.
When he asked them why they had run like that when one could have had all the fruits for himself, they said, 'UBUNTU, how can one of us be happy if all the other ones are sad?'
'UBUNTU' in the Xhosa culture means: 'I am because we are.'
