In the past few years, I've noticed more and more that whenever someone is waiting alone for something to start (e.g. a class, a party, or meeting friends and whatnot) if it's a young person, he or she typically has their phone out and is engaged in text conversations with friends. If it's an older person, he or she is probably more inclined to make smalltalk with strangers or silently wait.
Texting, and any communication technology, is a great benefit, and I'm not one of those fear-mongerers who say it's going to ruin civilization. However, when I see young people attached at the hip to their phones instead of learning how to entertain themselves, talk to strangers, or engage in some self-contemplation, I feel like that hinders their preparedness for socializing in new settings.
