wow, that's an excellent point. Social media probably almost entirely contributed to that kind of insular existence, or the idea that you could celebrate or proclaim your identity at the expense of recognizing or understanding others identities. Lots of social media posts and trends probably about "don't even talk to me if you sit next to me in class", "so awkward someone tried to talk to me" "we had like the same class and he tried to ask me a question...like I'm not texting".
Also, the nature of AirPods, phones themselves. I read a book that talked about AirPods affecting your ability to interact or connect with others, and cut that down. The author was a teacher and talked about how students before and after class are on their phones, but that is an effort to connect with people: without realizing they can connect with the people in front of them.
I am far from some kind of dancing extrovert, but I have studied and practiced and learned my social skills, sometimes on some Talented Mr. Ripley type of shyt, to where I can interact with people a lot more confidently, and across social classes with ease, which is one of the least understood aspects of upper class teachings.
