<human>: Can you provide a brief rundown of the text in within 3 sentences?

My brother has had a poor relationship with my mom since he was in his early teens. Lately he has been estranged from her. Essentially, it is because he can be very immature/childlike and because my mom is not respected by him or a strong role model for him. They both are not the most emotionally intelligent people in the world. However, I find my brother is worse than my mother in this regard.

My father and mother divorced when he was roughly ten years old. My father was not the strongest role model and died when my brother was in his late teens. My other brother [27 M] and I [22 F] are both younger than him. We get along with my mom and each other. However, our relationship with her isn't exactly warm and cuddly. She isn't the best mom in the world and is a poor communicator. Our family is far from perfect.

My older brother is quite reckless and spontaneous. He is quick to insult/criticize. However, he will not accept anything if it is directed towards him. He will lash out. I find my relationship with him is best when I see him infrequently. 

Part of me feels that he has some serious emotional issues. Hopefully they are not neurological.
