As the saying goes, or "a knife with a mouth and a tofu heart", will a knife with a mouth really have a tofu heart?

I believe that everyone will encounter such a situation in life. For example, after some people have said some hurtful words to us, they often hurriedly explain: I'm sorry, I'm a direct person, and sometimes I don't forgive others, but I really don't mean any harm. I don't want us to mind his behavior while explaining it. In fact, in our life and work, everyone is collectively called such a person? A knife in the mouth and a tofu in the heart? But sometimes such people are really mean when they talk, and there is no such thing as a tofu heart. Do people with knives really have tofu hearts?

I'm serious, but this may not be the case. People with sharp mouths may not have tofu hearts, because people like them will be said to have tofu hearts. Those who touch the interests in the eyes of each other because they don't touch their own interests, there is no such thing as tofu hearts at all. Coupled with the current social reality and the complexity of people's hearts, we can't simply think that people with sharp mouths are very kind and simple at heart. ? We can boldly imagine that people who can hurt you in language at any time, when your mouth or the other person's mouth is used as rice, are often trying to achieve certain results, or just for their own plans, because their hearts are already like knives, they will express their true thoughts and wishes, but even so, they should exercise self-restraint in words, and don't always find someone's scars to expose people's segments. If they are such people with sharp mouths,

From a psychological point of view, if he has a tofu heart, he will be very cautious in his words, but he will not easily say something that hurts others. People with a tofu heart are often kind and simply willing to think about others, so naturally such people will not have a knife mouth.
