To tell you the truth, my preference is strongly against cell phones. I don't even have a voice plan.

The thing is that I simply respect other adults enough to let them decide whether it's ok to make a phone call. We're all adults, we all know that loud phone calls are disturbing, and we all might one day have a great reason to make a loud phone call. Sure, there are some rude people, but why let them spoil adulthood for the rest of us?

To put it another way, large institutions should not concern themselves with matters of human etiquette. Rules intended to preserve good manners are almost always more harmful than good. Mundane human relations should be as informal as possible - any time constant formalization of our interactions is an impediment to progress.
