In front of every other person, you are a different one, but when you get to know each other, you will start to trust or hate them. There are many kinds of people around like, people who will judge you by your appearance and there are some people who are very kind and cooperative at times, although some will just ignore you. But every person is good in their own way... You have to be a different person from every other one.
