put that phone down and talk

Put that phone down and talk, for God's sake.
Sometimes I just want to yell those words at almost everyone.
I first noticed this when I was sitting in some café. I was distracted by a group of teenage girls who walked in silently. They were not talking to one another. Uff, teenagers, I thought. And why was I distracted? Because they sit down and continue to ignore one another while they had their noses buried in their smartphones. I swear they proceeded to text each other. That’s right, they were texting instead of talking. I was shocked.
It’s scary how technology is taking over. The other day in a hotel, I saw this couple checking in. After dropping off their backpacks in the room, they came back down, both with a laptop and they spent the rest of the day sitting next to each other (proabably chatting on Facebook), and not speaking to each other. The first question somebody asks these days when looking for a room: Do you have WiFi? Well, sad but true.
As I really don’t mind that we all have technology now and can stay connected but I DO hate it if you’re checking your phone at dinner, or during a conversation with me – what the hell are you doing? I mean, if you can’t pay attention, why should I?
I have on friend in particular who will come over to my flat, we'll sit and start having a conversation and the next thing you know he's on his damn phone texting back and forth, like having a full-on convo. Really? Can we talk? Are you married to your smartphone or what?
How sad.
And that situation where you are having dinner with a friend or colleague who can’t help but look at their phone every five minutes and reply. They smile as they type. I just hate that. Like, hello, I'm sitting right here in front of you!

One solution to this problem I’ve heard of is the phone pile game. Everyone puts their phones on a pile in the middle of the table. Whoever breaks and picks up their phone first has to buy the drinks or pay for the dinner. Seems like a good plan to me.
Any thoughts?
