When you find out a friend has been talking about you behind your back, most people either go and confront them or keep it inside and get upset. But both are a big mistake because when you confront them you create drama, and when you keep it inside you destroy yourself. Here is a psychology trick to help you handle this better. Don't say anything to them. Don't react. Just observe their behavior. Because someone who talks behind your back has already lost their respect for you.
