Well, I think it's very useful to have a cell phone with you when you leave the house. It comes in handy in an emergency. Just last weekend I was miles away from home, on my way to visit friends who have moved to a small village at the border with Germany, when my itty bitty lil' car suddenly started roaring like the Lion King. Oh-oh... my exhaust pipe had snapped and was dancing up and down like a water hose!
So, I don't leave home without it!
