For example, you cannot drive a car with only four tires and a body. You need an engine to start your car. Same thing with friendship. You need trust to build friendship. Many people in society don't trust each other because they lie to each other. Another factor is a wife and a husband. If they don't trust each other then marriage is meaningless. A long time ago a friend of mine had an uncle who got married. But they didn't trust each other. They would argue, etc. This led to divorces because they didn't trust each other. Trust plays an important role in our society. If there is no trust, there is no friendship or any type of relationship. It really affects society and our future
