I have one, and people ask "why do you have a mobile when its never on" it is on, but not always where I am, maybe charching somewhere.
I totally agree with people NOT having the phone on at the table, my Grandchidren came with their parents the other evening, armed with their mobiles of course, we were about to eat, I said "this is a mobile free zone" they looked at me, and put their phones away, but couldnt wait to leave the table and spend the rest of the evening lying on the sofa looking at their phone. Another one; we went spontaneously to a neighbour just for a chat one evening, the Husbands phone rang and he proceeded to talk,at the same time as my Husband stupidly had asked a question, and immediately the Wife got out her phone and started to GOOGLE, so there WE were sitting on our own, while host and hostess merily ignored us until phone conversation was over, and the GOOGLE had done its job, I was furious, inside, and thought how rude people have become, because of technology. Ranting over!
