Agree that the same applies to text & online discussions.
I tried to teach my kids that when there is a complication in a discussion, it is better to pick up the phone and talk it over to smooth differences, but they retorted that calling someone when text is expected is simply rude in their world – you are imposing your timeline on the other person, rather than letting him respond when he feels like that. By extension, goes to many other interactions in business world, where people make decisions about admissions/shidduchim/war targets based on what it currently says on their screen.
In all of the interactions, just try imagining the human being at the other side of the car window/internet connection/gun barrel
