2 apaches and a navaho

These three guys were interested in what I was up to when I stopped at a reservation store. They were very friendly, and the two on either end were pretty inebriated.
Regardless, they spoke reverently of their people and their land... If not reverently to each other. They each told me their indian names which I cannot remember and cannot pronounce. The two on the left are apache, the one on the right is navaho. The navaho guy was mocking the long haired apache to some effect. The apache then responded by saying, 'shut the hell up you stupid fucking navaho.'
Apparently no tribal wars were begat... They seemed to be pretty close friends.
