He immediately got angry with me and raised his voice. When he raises his voice, I respond in kind then it becomes a fight. I cannot just sit back, be quiet and calm while he's trying to start an argument. I get angry because of the way he's behaving. It makes my blood boil when he raises his voice.

He claims he has a different recollection of how this happened. He claims that I got angry first, and then he responded to my anger.

I don't recall it that way. What I recall is that I simply asked him for money and he reacted in anger.
