Mobile phones

Mobile phones are useful, but the only time I remember to take mine with me is when I go to France - and then it's only switched on every couple of days or so just to check that there has been no emergency that requires our immediate return. Actually, I do use it to book a table at our local restaurant. I have to book or there is no guarantee that it will even be open, and there is often no point walking to the bar at lunch time as the owner is quite likely to be somewhere else in or around the village with the bar open and unattended. And as for sending a text message... Well, I did try once, but couldn't get it sent and I've never tried again.
