My understanding of education is that when a person enters a closed room, he just knocks on the door and asks if he can come in. Then you can close the door behind you when you go out, and the action must be light. Sometimes, I often need this kind of thing. In the office, all the teachers were explaining their work to the students, and then suddenly the door creaked open, and a student walked in without saying what he was doing and strode to the desk of the teacher he was looking for. This will interrupt other teachers and work, and then the content organization language will be reorganized. In my opinion, such behavior is uncivilized. In my opinion, before entering a closed room, the first thing we should do is to knock on the door, not push it open. We have been taught this by teachers since kindergarten.
My understanding of being a parent is, thank you, I'm sorry. It's really not difficult to say thank you and sorry. On the crowded stairs, it is inevitable to meet some people, step on her feet or bump into her shoulders. At this time, there are many people, and everyone is a little upset, plus being trampled or touched inexplicably. It will be more annoying. At this time, an apology will be like a spring breeze, blowing into the walk of yourself and others, making others feel like a spring breeze. After you need help and get it, it is simple to say thank you, but at least you can continue the happiness of yourself and others.
My understanding of education is that language civilization is not dirty. I wonder how many people have seen this phenomenon. Clothes are fashionable young people, unconventional, unconventional. When you open your mouth, those words are as disgusting as true. I don't think so myself, but I'm still complacent. In fact, such people are very disgusted in the street. Mom and dad teach us to speak, not so that we can say a lot of dirty words, but so that we can say things that make others and ourselves happy. In my opinion, such people completely forget their parents' education.
