Granny was annoyed the other day to discover that her mobile phone bill had risen from £13 per month to nearly £17, with no notice what-so-ever. Although, if truth be told, just why Granny has a mobile phone is beyond me because it never leaves the house. Many a time, I will ring her and get no answer and she later tells me that she was out. “Where the hell was your phone?” I ask innocently, only to be told it was sitting on the kitchen table – it’s normal home. I am sure it would prove so much cheaper to just use the house phone!
