Is it okay to speak directly?

Not good! Speaking directly can easily offend people. It is unwise to make enemies for yourself. Sometimes if you are tactful, it will be easier for the other party to accept it if they don't notice the malice. Speaking too directly also seems to be incompetent. Even good friends dare not reveal secrets to you because you can’t keep them. In short, you still need to learn to be more tactful when speaking to others. Not to harm others, but to protect yourself.
