Having balance in life(HARMONY) is the key to having good relationships with people. In other words, you have to take the good and the bad with all people you encounter. Talking to strangers is the only way to build a foundation for any type of relationship. After all, everyone is a stranger until you get to know them. The best way to have a harmonious relationship with people is to respect their opinion and them as a person. Everyone is obviously not going to agree with one another. That's what makes relationships great: just agree to disagree.
