Roaming Out West

We saw something interesting the other day. An older man, sitting on the median at an intersection. He was 60-ish, thin wispy white hair, no shirt but wearing an orange reflective vest, khaki pants, and sandals. He had a piece of cardboard upon which were scribbled in his finest Sharpie penmanship something about how he was both homeless and hungry, and his god would bless those who gave him money. (For reasons I have yet to figure out, but that's not the point of my ramble.) He was seated, and hunched over. Not from weakness, hunger, or overwrought despair at his lot in life as you might think from the words on his sign. He was slouched, as he was talking on his friggin cell phone. Granted, I'm assuming he was talking to a human and hadn't just picked up a discarded cell phone and was finally engaging in a less obvious communication with the voices in his head. I guess that's possible, but the posture was a partial attempt to block the noises of traffic. Something not really necessary when the voices are internal. Which leads to a more puzzling question: do you have to pay roaming charges when you're talking on a cell phone to the voices in your head? Sure, they sound close, but if they're extra-dimensional, that would add up to a hefty phone bill at the end of the month.
