How can our own culture limit our perception of other?

The way that our own culture can limit our perception of others, in my case I am a very modest person and I work as a servant of Baba. I am a very kind and good person. I really love my son Hassan, but it’s hard to express my emotions to him. Our life is hard, so I want to keep my son with a life that he deserves. We are poor, and I am an ethnic Hazara. By the way my life is and the way I see it, our culture can limit our perception of others because every culture is different, and some are more strict than others. Depending on your culture your perception of others can limit by not knowing exactly the other person and how he is. In my case we are poor, and I got abused a lot. Culture depends also in social classes, so I will say I am in the lower one. Polio affected me when I was a youth and I got severely damaged in one of my legs and suffer congenital paralysis of my lower facial muscles. The perceptions I have on others is kind of bad because people treat me bad and only because of the culture I have.
