Be diligent when you need it, kick it open when you don't need it, and "stab the knife" behind your back! Is such a person a friend? What should I do?
I dare not say whether such a person is a friend, but you already know him, and you are still hesitating about whether he is a friend or not. How can I treat your IQ? As for what to do, now you should have a clear choice! ? Add a sentence: the heart of preventing people is indispensable, and the heart of hurting people is indispensable. The villain has his own wicked mill. If you are not a wicked man, don't get involved in this muddy water. I hope these unpleasant words will help you.
