The options for communicating these days are incomparable to only a few years ago. FaceTime, SMS, Viber, WhatsApp, email and in this case Skype are all (relatively) easy and cheap means of communicating with somebody who is not within earshot and we use them all. Just a few years ago a phone – mobile or fixed – would have been the only option and that would have amounted to an expensive luxury. Try to explain to the kids that, when we first went overseas to live some 23 years ago, the only option was a weekly, handwritten, airmail letter; the response is utter incomprehension!
Regardless of all these advances though, communicating means having somebody at the other end to answer – and even in this modern age, that can still be the frustrating part!
