Well, we have no mobile reception in our house - which is leading to ever more interesting complications. I can use my mobile if I walk along the road and up the hill a bit- but usually it is off unless I am out and about and all it is used for it to make and receive phone calls.
I watch people who are glued to their phones and I despair, I really do. The worst are the mums who I see sitting together - all typing away on their phones whilst their babies/toddlers watch them from their push-chairs. The children are not learning to TALK!
