“In our constantly developing world, we have to learn to adapt to change. The fact that we are so dependent on the internet is scary. But the fact that you, as an adult, are struggling to keep up with us and the internet, does not give you the right to say that the way we are learning and growing up and socialising is wrong and we need to go back to how you used to write letters to your friends or call them using the home telephone. Neither way of living and socialising is better, just very different, which I think is the main cause of the older generation not tolerating the use of our phones.”

Anecdotally, I’ve always found that it’s the people / teachers / ministers etc who complain the most about “young kids always being on their phones” that leave their phones’ ringers on (at full volume) and have no problem answering a call (after a few rings, of course) and having a very loud conversation despite the context or their situation.
