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

Sometimes the expression may be inaccurate and easy to cause misunderstanding. In fact, this is the case, which can show that you are a very straightforward person. You don't have to explain anything. When you realize this, smile at the other person, make compensation, or listen to what others have to say, and then change yourself. But I don't think it's necessary. Just have a clear conscience. It may take some time for others to accept your expression, but it also takes some time for others to realize that you are wrong.
