When dealing with others, you always get the most sincere and realistic experience, which is ruthless injury. What is this?

You think you are sincere and honest with others, but others don't think so. Instead, it has brought you heartless harm. If only one person treats you like this, it means there is something wrong with the other person's character. If people around you treat you the same way, it's your personal reason. Self-reflection, where I misbehave, sometimes being too sincere is also a sign of cowardice and incompetence. That's why you were hurt mercilessly.
