Explanation:

The lines have been taken from Amigo Brothers written by Piri Thomas. This short story is bout two friends who grew up together with such enormity of friendship and brotherhood that they started imagining each other like real brothers. The commonality that they shared was their love for boxing which they loved to fight. It was an outlet for both of them from the negativeness that was highly prevalent in that part of the city. In Paragraph 45, Antonio is passing through a dilemma where he has to figure out the outcome of his boxing match with his brother - like friend, Felix. He tries to console himself by saying the friendship and sports shouldn't be mixed up.
