“You don’t understand”, this is a key phrase we hear from people who wants to put us down, especially when they repeat it. This is a phrase of attack. Never say this. But in case you must say this, think 100 times before. Because it can be that I did not explain something well and that is why the other party did not understand. Then when someone is saying this to you, “You don’t understand”, don’t defend yourself. Because often this phrase is a sign of desperation and impatience. Don’t doubt your capacity of understanding or yourself. Be calm and understand the intention of the person. Then you will see the whole picture. So, whenever you hear this phrase, “You don’t understand”, it is not that you must understand what he or she says, but that you must understand the person who says that.
