Building relationships with others is an important skill we need to learn since we were born. Throughout our whole life, we meet different people every day at work, at school or other places. Someone are good at building a good relationship with everyone, but the others are not, they even feel scared about social contact. According to my experience, a good relationship is based on balanceing the benefits of both. If people just want to get benefit from others, they don't know how to respect others.They are selfish. I also saw some people who just considered other's feelings while building relationships with others. They tried their best to make others to be happy, but ignored themselves. They liked the owner and a slave. So,my best relationship advice is that you don't need to build relationship with the people who look down on you, you are not supposed to play up to others.
