M and I went to a restaurant in Fortaleza last night and were enjoying an excellent dish called Escabeche de Camarao in a fabulous restaurant called Coco Bambu. After a while, a couple with three children came in and sat down at the table next to us. For the next hour, with short breaks taken to eat, the mother and oldest son spent all of their time ignoring the father and the two youngest boys whilst they played with their smart phones, no doubt admiring all their selfies, tweets and emails and generally being totally mesmerized by this new age form of hypnosis. Is this another form of addiction? And is their any treatment?
