Who is the Real Buddy Bolden?

Buddy describes the moment when he is heading back to the house as he says: "In the late afternoon I walk back along the shore to the small house and it is against me dark and shaded." (68) He says this in such a cold voice, that we infer something happened previously that he is not proud or scared of. We know this since the house is "against [him]", (68) meaning it isn't a warm moment. "Dark and shaded" (68) are key words in the sentence since they give us a negative perspective about Buddy and the house. He then makes a pause after he says "Robin and her friends". (68) This permits us to deduce he speaks in a cold way, implying that these characters are part of the conflict. Buddy then says: "I am full of the white privacy. Collisions around me. Eyes clogged with people." (68) By saying this, he means there will be problems around him, supporting our previous idea. We are then certain of our assumptions since Buddy describes the situation that had occured. "Yesterday Robin in the midst of and argument flicked some cream in my face. Without thinking I jumped up grabbing the first thing, a jug full of milk, and threw it all over her." (68) It began as an argument but things got out of hands, leaving the situation in a negative way. Based on what happened, we also know the characters have a  close relationship  since throwing food to others is an act that only people who have trust between each other would do. Besides, the fight really affected Robin. Buddy narrates the moment by saying "she stood by the kitchen door half laughing and half crying at what I had done. She stood there frozen in a hunch she took on as she saw the milk coming at her."(68) She kind of laughed but also cried because she cares and was hurt by this. She was surprised that Buddy would do that, therefore stayed freezed. The way Buddy describes her face lets us see how he also cares about her. He thinks she is "beautiful"(68) and stares at her since he cant believe what he had just done. Based on this paragraph, we can see that Buddy is an impulsive man who really cares about Robin.
