Male Loyalty Is...

Gregory David Roberts, novel "Shantaram" (2003)
"For his part, Abdullah never told me what the fight against those men was about, and I never asked him. The one time we did talk of it, years later, he told me that he began to love me on that day. He loved me, he said, not because I joined the fight, but because I never once asked him what it was about. He admired that, he said, more than anything else he ever knew about me."

The narrator had joined in on a fight to defend his friend Abdullah. His friend was in danger and needed him, and that's all he needed to know.
