I agree, it's all a question of balance… and, in my opinion, people really must be more attendant and listening to their surroundings = be it the people around them, Nature, city-life… – and less to their phones/music on the phones etc. For example, whenever I go out, I NEVER take headphones with me anymore. It's out of principle – I totally hate to see, how more and more people grow to be so isolatedly detached from their surroundings by that horrendous invention, becoming autistic even. There care always countless excuses for that, but I accept none.
Also, when I meet with people, I'm with them. And, from the moment we meet, the phone is turned off – or, at most, used as a camera to photo a restaurant-meal or suchlike, but NOT for any talking / messages etc., NEVER.
