There were 2 guys who are close to each other. One day, the first guy met a girl and started to fall in love with her. He courted the girl but the girl seems don't want to be in a girlfriend-boyfriend relationship in a way that she treated the 1st guy as a friend. The girl cannot explain to the first guy about that. One day, when the 2 guys are talking to each other, the girl met them. The first guy introduced his buddy (the 2nd guy) to her. And the communication between the 2nd guy and the girl started. They started talking and talking until such time the topic goes in the courting of the first guy to her. She explained to the 2nd guy that she only treat his buddy (the first guy) as a friend and she does not know what to do. The second guy said that she must tell the truth to the 1st guy in a way that she will not make his heart broken but she asked how? The 2nd guy replied that she must use nice words. Later, the girl talked to the first guy and she explains everything that she does not love him and she treat him as a friend. The first guy was so sad and he believe that she was influence by his buddy and he plans to court her, not knowing that his buddy was just trying to help her solve her problem and was treating her as a friend that needs help. The 1st guy had a quarrel with the 2nd guy saying that he wants to court her also making him a rival. The 2nd guy explained everything but he (the 1st guy) do not listen. Question: Does the first guy have the right to get angry on his buddy (2nd guy)?
