Describe a person you dislike, and explain why you feel his way about him or her

There is no such person who likes everybody. I’m not different. There are couple persons who I dislike. One of theme is a man but I can’t say that I hate him. I’m not going to tell that person name.
He’s very arrogant man. He was always speaking to me as kind of lower species of human being. That man talks and thinks about him self like about very intelligent person, but he didn’t behave so. Each thinking human who sees older guy expects from such a man some good, or even very good, manners, especially when that man is on responsible position in our society.
When I’m in a new situation I’m trying fit in. But this guy start, at the very beginning, attacking everybody. First of all what kind of man, on high intellectual level, curses in a public place? What kind of teacher uses slang in his speech? I think it’s not a good example of behaviour. I don’t want to insult anybody, because I’m not saint, but in my eyes such kind of attitude is inexcusable, especially at school. Contact with so young mind must be gentle and thought over.
But on the other hand he had great knowledge. When he wasn’t at classes he was nice man. So that more strange that he was showing to faces in his life. It’s difficult to judge such human. Maybe he should not show his student only the bad sight of his character. There is nothing wrong in showing filings.
To sum up I had to tell that no one is perfect. I’m also not perfect. That man has never done something wrong to me, but I don’t like his attitude to his profession. I wanted to learn that subject which he was teaching me, but he was pushing me away from this, not only me but also everybody alls. I don’t like him, but it’s only my opinion. Maybe in some one eyes he was a good teacher but not in my and nothing will ever change this.
