The real use for cellphones

Besides singing loudly where others can hear, have you ever dared to think out loud? Start a long conversation with yourself? Nowdays it's possible: just get an old defunct cellphone and an earphone. Sit in the park with the cellphone in your lap and say anything you want, right out loud. Nobody will care. (Just don't dare to try this WITHOUT an obvious cellphone and headset!) Hmmm. Even better. Just wear a headset alone, but with the plug dangling loose in your lap. Passersby will assume that you have a cellphone. But perhaps one or two will look more closely, realize that no cellphone is involved, then suddenly stop smiling. And back away from you carefully.
