Haven't the teacher arrived yet?

There is a form to ask for a signature from a teacher. I went to the teacher and found that the teacher was absent. When I came back, I met another person who had already signed the letter. The other person asked with concern: "hasn't the teacher come yet? ", A: "I will go back tomorrow ."
The teacher didn't come and asked you how to do it. My answers have two simple understandings: 1. I went to the teacher and found that the teacher was absent. So I planned to go again tomorrow. 2. I didn't go to the teacher and planned to go to the teacher tomorrow. If the person you ask is very concerned about this matter, the two understandings give the question a very different impression, and the misunderstanding arises. The root cause of misunderstanding is communication barriers. The root cause of communication barriers is the excessive extension of problems.
Reflecting on yourself, the problem of excessive extension of the question is your habit. This problem is the most technical problem. When someone asks how and answers why, the question is confused, the result is that the questioner's confidence is under a blow and acts as a kind of drug killer.
Further, the root cause of the problem of excessive extension of the question is that you are always pursuing one step in place. To put it straight, it is called "once and for all. The links between personnel are inextricably linked. The world is always evolving in a changing movement, and the pursuit of one step is in place. However, we must take a clear picture of the situation and put our eyes at a high level, but our actions must be realistic. It seems that the pursuit of one step is often a manifestation of the perfectionist (perfectionist is not a comments, and he is not boasting about himself), and in fact all development is gradient rather than mutation, one step in place is not mature, and we should have the patience of "accumulating small wins for winning.
