Why am I always stupid, always unable to understand the true meaning of others, and sometimes what I say doesn't fully express my meaning,

The old saying "think twice before you act" is still very reasonable. No matter what you say or do, try to think about it in your mind and think about it in many ways. Only in this way can you think clearly about what to say and express your views more correctly, so as not to give people a feeling of ignorance. Because in the process of oral expression, you must first know what you want to say and what you want to express. Only when you hear clearly can others hear clearly and understand. In addition, if you don't understand what others really mean, I suggest that if you don't mean by innuendo, you can tell them clearly and sincerely, "I'm sorry, I don't know much about these things, and I don't know much about them. Can you be more specific? Thank you! " If you don't know anything else, it depends on the score.
