My mother and brother have same temperament when judged conservatively. I think, the two of them are emotionally immature. Whatever they feel and their perspective is always the truth. They are fond of "certainty" of things. "You are always like this," "You are wrong," "I the one always" are some of those examples. My mother is assertive, my father is not. He is more like a water. I think I can say, me and my father have the same temperament. But I know that their favorite child is my brother. They always follow what he deemed he wanted/need. It is kinda my fault too though. I'm not the type to express what I want/need to my parents. I have to learn to give requests throughout the years when I learned I am helpless and not being the biggest supporter and cheerleader to my life. I guess, we can never become close brother. Unless both of us grow up better and fix our own faults. No longer hoping though because my focus will be me being a person who stand by my own.
