The greatest difference between people, I think, is their own cognitive level. When leaving for home during the holiday season, I always have conflicts with my mother -basically on world values. And I understand that we grew up in different social environments, but she always forces me to behave in a way that she thinks is right. She always squabbles with me on trials?., so I have to find a good job ASAP after graduating and take care of myself with my own salary.
