This goes back to ancient times, and there is a dialect of speak that seems kinda alien to our more modern interweb culture.
This is where the phone piece places the rather zombie like state in a group of friends and whatnot. As an outing would go, meeting up with friends, you probably gathered the idea through social media. Just to stay in the realm of social media, everyone stays in their phones to keep up with times, not realizing their friends are right there.
This is why I do not really own social media, ie; facebook, instagram, etc... etc...
