I've had a window cleaner on his ladder cleaning the bathroom window and talking on his phone at the same time :p
Thankfully, talking on your mobile whilst driving is illegal here, although I know a lot of people who do it anyway.
I have a mobile which I do like very much, but I don't usually call on it, I'm more of a text person. If I call someone on my mobile, it's usually just to tell my parents that netball practice has been cancelled or something, if I want to call a friend, I use the landline, much cheaper. ;) Mobiles can be a good thing, they can help to reunite separated mothers and kids in a busy crowd and are perfect for emergencies or calling home when you are abroad, but, sadly, they are also the cause of much theft, muggings, and even stabbings :(
