I am sorry this is infuriating to you, but NO ONE has my cell # except my husband and kids. I think my dad might have it. So, who would call me? My kids are grown, and if they couldn't reach me, they would call the house.
Well, I do have 2 other people who have the #, but they know not to try and reach me this way. One of them has it for when we lead rides (it's on then).
My emergencies would probably revolve around cycling; if I was in trouble.
Ring tones drive me nuts. Who wants to hear someone's stupid music in public? It's not that I am screening calls. It's that I am perfectly happy waiting until I get home to make plans or talk to a friend. And, I do not call them on their cell phones, either.
I know this is a generational thing, although many of my friends seem to be obsessed with their phones.
I am not the norm, I know. I am generally a technology philistine who believes we would all be a lot better off being so connected.
