Do you understand? Don't you understand? Generally speaking, those who understand will understand without bothering to explain. People who do not understand will not understand how much they explain. In other words, there is no meaning in the explanation. Well then, there are also a few people on the boundary line that do not know whether it is understand or do not understand. But you know, if you are with people who do not know unless you explain it, I think that the rhythm will keep going crazy and get tired. So, I want you to listen to those who understand without explanation that it makes it a story of this familiar tone of voice. And just want people to shake their heads to nod. That's all. Did you understand?
