What are the obvious characteristics of a kind-looking person with a "dark" heart that can't be hidden completely? Feature 1: it is easy to be jealous and can't see others. On the surface, these people seem friendly, but in fact, they are often jealous of others. Seeing that you are not doing well, he may not help you, but as long as you are a little better than him, you will be jealous and try to discredit you and pull you into danger. Most of these people who are not good to others are narrow-minded and petty. Seeing that others are doing well and are not modest about their own advantages, they are resentful and always want people to stumble.

Feature 2: I don't know how to be grateful. I patronize the immediate interests and get along with people. I pay the most attention to being grateful sincerely. On the premise of taking good care of our own interests, we should not forget to balance the human feelings around us, properly invest in interests and make profits. But some people don't know how to be grateful, and all they see are benefits. When you have practical value, they will flatter you, hoping that they won't really pay with you. But if one day you encounter difficulties and can't continue to help him, he will immediately tear his face off. No matter how much help you gave him before, he will always forget. In the eyes of such a man, you help him because you owe him, but don't expect him to help himself at the expense of his own interests.

Feature 3: Words don't count. I often say one thing and do another. Some people habitually lie. We always say one thing and do another. They are good at talking and making all kinds of promises to you, but they never put them into practice. Such people without credit are simply not worth getting along with. They can make a commitment directly, but they never want to entrust themselves to you. Make friends with such a person, he can't help you in a pinch, and he often makes low-level mistakes because he agrees with you in a pinch. This kind of duplicity, duplicity, or try not to make friends. A truly loyal and frank gentleman will never deceive his good friends with perfunctory promises.

As the saying goes, friends have many roads, but opponents have many walls. Although there is some truth in this statement, it is not entirely correct. Only after experiencing such a bad person's frame-up, will you find that the more good friends, the better, but whether you can be honest with each other and whether he is worthy of your trust. When you are alive, making good friends can get a lot of help in your work and life. But if you make friends with such kind people, you will definitely get hurt in the end.
