My cell phone just rang. I didn't recognize the number, but I knew the area code was a Cleveland number. Turns out my 75-year-old grandmother has a cell phone. And doesn't know how to use it apparently, since she meant to call my Aunt Kathy and was shocked that she'd mysteriously reached me. Please explain to me why my technologically-illiterate grandmother has a cell phone and my 27-year-old gadget-obsessed boyfriend doesn't.
