The truly frightening thing is not the person who talks badly about you behind your back, but the one who passes the words to your face. Because the person speaking badly often only harms behind your back; while the one passing the message, fully aware that these words will create suspicion, anger, and conflict, still chooses to bring them to you. He may not be helping you; many times he's just trying to see your reaction, amplify the conflict, or even influence your judgment through others' words. If a person always likes to talk about others' right and wrong in front of you, one day he will definitely talk about your right and wrong in front of others. So, to see a person clearly, don't just look at what he says, but also at why he wants to tell you these words.
