I don't know how to speak. I always make people angry when I speak. What should I do?

Sometimes the expression may be inaccurate, which may easily lead to misunderstanding. In fact, it is such words that can show that you are a straightforward person. You don't need to explain anything. When you realize it, just smile at the other person and make amends, or listen to what others have to say, and then change yourself. But I don't think it is necessary. Just have a clear conscience. Maybe it will take some time for others to accept your expression.
