~ Conclusion: If you do not have internet, you can not contact "if you arrive properly ~
I feel that experiencing the world with the Internet, it is understood that it is an unavoidable existence for modern people who have become "natural".
E-mails and searches are alternatives to the "acts" that we did using different means ("telephone" or "library etc.") when there was no internet. However, the Internet not only created it, but also SNS and LINE, "acts" that had never existed, and now they are the center of our communication and I realize that the Internet has appreciated again.
