About identity

Everyone has their identity, because everyone is difference. There is no one who is same with another, in the point of view of medical science there is no couple people's DNA is same. Individuals indentities include Id card, DNA, sex, ect. But in the society has a phenomenon what is people always gauge individuals' identity by their surface.
These days, we read a story that called indentity. From this story, i can know lots of things in the society. Same person with difference dress up, and get different treatment. What a reality's society it is. Today, Darya told to us her story, she said when she and her friends went to a restaurant if they wear as uausl, the waiter said something bad for them. But if they dress up, the waiter will think they are foreigner and be good for them. Just same as the story Identity, the protagonist is the rich, but he wear jeans and looks like bad guy. So when police saw him, the police don't think he is a good man that occur the tragedy. And also i think this story is irony person who is objective.
Identity problem also happend in racial. In small part, when we take bus and there is someone wear poor and come from coutryside, you will not like stand behind with him. But if the person who is looks beauty and rich, you will think it's ok. Same as in foreign country, i have some friends, they always talk about racial discrimination. But in my opinoin foreigner said some bad word to us same as we don't like stand behind countryside poeple in bus. Because we don't in same level so that we cannot let other people get same idea with us.
Almost individuals know that we should not only saw the surface to decided the person is good or bad. But more time we cannot do like what we want, because person has an instinct that when we saw bad thing or person, we will far away from them.
