Yes I feel people can be insulting in the way they use their phones too!
I remember answering the door to a friend and when I opened the door he was talking on his phone, not to me! After this I instituted a box by the door for him to put his phone in when he came to see me, in case it rang - and he did get trained and more civilised....
Lately I have been niggled by my daughter being on hers when I get to her house, I am working out what to do to show her that I am really upset sometimes by this. I may go back and sit in the car!
Yes I have a phone and it can be a mental lifeline, as I can speak to her free on it with a family arrangement, £5 a month - otherwise I don't use it much, but am glad of it in the car for emergencies. I resisted getting one for ages.
I do remember the first times I heard people on mobiles.
The very first time, it was a builder - on the top of a roof across the block, telling all and sundry his business! And in a pub with a group, only two of whom had phones then, they were both on them - so I commented that they were phoning each other to show off.....(yes, this is a while back, isn't it?)
And a time on a train, with a woman across the aisle talking to various people including husband - I was annoyed at first, then realised as she went on that she wasn't going where she had told her husband she was....she was going to stay with a friend...male?? no, female...pity she got off before I discovered any more....
I think I have a love/hate relationship with them.
