Unfair silver price per ounce

I have read an article yesterday that made me think about the way people behave. Do you think that we can influence our behavior or that we can^t change our character? It is really interesting for me. Think about it for a second. If the truth is that we can change our life and character and it is easy it means that we shouldn^t be acting in a wrong way. If we do than we are the only people responsible for that. Do you follow me? I have been thinking about it and I would like to believe that it is possible. On the other hand when I look around me at the people that I live with I don^t think that this is the case. There is this one man living in my flat who is always rude to the people. Once a neighbor of mine have told me that he has a jeweler^s store. I was walking past it once and have noticed the silver price per ounce that was on the front door. Trust me, it was an unfair price. He must be the same in business as he is in life. Rude and treating people without respect. I think that it is terrible and it is also a proof that he is a bad person. He can^t change his way of acting and this silver price per ounce is just an example of how he behaves. Do you know any people with similar problem?
