The last time I went to New York, with a group of girl friends, I decided to donate my mobile phone to the needy of Heathrow Terminal Five.
I went days without people being able to get hold of me directly, without being able to put a succession of smug pictures on Facebook and without having a phone almost surgically attached to my hand.
Being able to look up stuff online is second nature to me now.
This trip I’ve had my phone out and used America’s free wi-fi to book lunch venues and sightseeing trips.
But mainly it’s been a glorified camera.
I’m happy with that, reassured that I don’t need to be contactable and that just the odd smug picture on Facebook will suffice.
