I have never understood why some grandparents are so strict with each other.

I also have an eccentric grandparent, especially my grandfather. These days, we went back to our hometown. My parents were away, only my grandparents and I lived there, and my sister. Because I have a smart phone, I can video with others. Once I kindly asked my grandfather to video with my uncle's son, that is, his second grandson. My grandfather never closed his mouth when he saw him. I understand, I understand. I didn't expect grandpa to say a lot of ugly things. What, you study hard in the future and surpass your sister. He is a girl, useless, you are the pillar of our family. After listening to it, I didn't say anything, because I knew that if you couldn't bear it, you would make great plans. I didn't expect him to talk more and more vigorously, completely ignoring my feelings. After that, I will go to the online class. Not only did he not give me his mobile phone, but he also scolded me. I don't care about these old people. To make matters worse, my uncle and brother. My uncle encouraged my brother to scold me in front of my grandfather. My uncle really did all the bad things, and so did my grandfather. Their RV was originally mine, and my grandfather forced my father to give it to my uncle. Not only did my uncle not know how to be grateful, but once his father was injured and needed money badly. My uncle said that even if he had no money, we wouldn't care about it with her. I also took my mother-in-law and others to Sanya to play. Causing my father to get sick. Unexpectedly, my grandfather paid more attention to my uncle and ignored my father. Why is this? The reason is that he caught fire when he was a child. He played by himself and burned and disfigured his face, but it has nothing to do with my father!
