In the life of brother and sister, being a good brother needs to pay attention to many aspects. First of all, when you were young, you could be a good brother without bullying your younger brothers and sisters. It is certain that two people often have conflicts because they are not sensible when they were young, and eldest brother has absolute advantages in strength and psychology. Therefore, you will often bully your brothers and sisters. If you don't bully them, they will treat you better. When you grow up, the feelings between brothers will be better.
Secondly, we should learn to protect our brothers and sisters. My father was three brothers and sisters when he was young. They were bullied outside, and eldest brother helped them out. So their brother and sister are very close now, so I think this is a good brother who can protect his family.
Finally know how to share. Although everything in the family will be average, some things may not be average, so at this time, I will ask my brother to be generous and give it to my brother and sister or all of them. This is what a good brother should do.
