I think it's an interested question. The answer may be true or not. We must to admit that not only man but also woman like a good looking people. They are attracted to us directly or indirectly. We will have different emotion and behavior when we meet them. It's usual. The same with rich man, facing with rich man, we like them if they are ethic and friendly. We don't like them just only for their money, but if you meet a poor people what do you do? Can you do or think the same with rich man and poor man. Absolutely, not. Don't try to lie yourself. However, it's not your fault, it's your emotion and we have to accept it.
Like or love a person is not a mistake or crime.
