As I sat down to write this, my youngest son phoned from New Orleans asking where to go for the best beignets. I described how to get to our favourite place, then he sent a photo of the shop frontage to be sure he had the right place. Ah, the modern phone!
When I was a boy, I thought I was smart because I mastered the prehistoric, steam-driven telephone. Not that it was difficult; there was button A and button B (which, from memory, you only pressed when the other party answered) but the rotary thing with holes for your finger could get a bit tricky, especially if there were lots of 9s in the number.
Of course, it was in a red booth. We didn't have a phone at home.
The biggest difficulty you might face was that the phone could have been vandalised, in which case you had to walk a considerable distance until you found one nobody had tampered with. This could mean that, by the time you had made your call, a lot of time had elapsed and a lot of distance had been covered, so you were reported as missing and the police search was on.
These days you carry your own phone with you so you don't have to walk far but you do have to vandalise it yourself - easy enough to do if you drop it on a concrete floor. And today it does so much. Just think of the services on offer: phone calls, texting, voicemail, Viber, Snapchat, Twitter (on which you can tweet), Facebook, Instagram, Extragram, Gorillagram, Rolypolygram, LinkedIn, Fast Post, iTunes, Skype, Tweetface, Twitface.
