they are already.....teens grow fast!!
turn off your computers, let your tablets and stuff at home and call your friends, and go for a beer. And if you are far away, send postcards, real ones, you can find pretty fancy ones out there.
And if you don't see people for a while, it's ok too. Once you meet again, you won't tell each other: i know everything about what you did, what you bought, about when or where you took a leak or went for a p...p, who you don't like, who you like, whatever the [censored] facebook predicts you to do in a couple of months or years because they know EVERYTHING....
so you'll sit down, with a beer, or sth else, talk about some stuff, be happy to learn something new or not and see everything is fine, or not, however, you interact.....for real.
PS, isn't google+ the same thing?
