It's funny isn't it. Whatever did we do on buses? How much the world has changed in the last 30 years with regards to technology and our permanently switched on state!
I personally turn off all notifications on my phone and the ringer is always off at night. I actually enjoy the fact that here in Thailand, no one is going to call me lol......I call my Mum and friends a couple of times a week on Skype and I might get an odd call from the wife if I'm out and about but other than that, nothing!
I like the silence, and turning off notifications for all apps means it's my fault if I pick up the phone and look at it.
Seriously, what the hell did we do in the 80s? 2p and 10p coins at the ready!
