Not so smart..

Fact, when walking on a pavement you are more likely to have a head-on collision with a phone user than walking in dogshit.
The permanent face down, the cupped hand that can't let go and the cross-eyes if they ever bother to look up. Maybe we are all guilty of it.
But a pet hate is the smartphone appearance at weddings. Now a common occurrence, we all need to know the latest gossip, football scores, and news-worldly events at your fingertips. But come on, at a wedding of a family member or close friend? It's ruining a photographer's pictures! Whatever happened to conversation without an urge to show off your dog's latest trick or baby's recent gurgle in the gallery of thousands of un-deleted images. 
What's worse is the "can't let go of my phone" attitude in group photos. When was it so splendid to see best mate Bob, bride with groom and a gleaming Samsung iphone?
A bowed head searching for some source of entertainment on the screen will not be photographed by me. 
I once was sat a guest's table to eat (I was invited to do so, don't worry!) and had the non-pleasurable silent experience of a company of mobile phone users. The whole table, two were watching a non-league football match being streamed from another phone! Was that more interesting than attending this wedding? Well, maybe...but you are invited and that respect should be taken seriously.  
I'm old-fashioned to presume you can survive without a gadget for a few hours until the next time I bump into you in the street.
