Completely off topic, but the title reminded me of something that happened when my son was about 9yo. One day he comes in and asks me what the holes in the walls were for? Holes? What holes? So he brings me over and points at an empty phone jack. I said, "Oh! That's to plug in a phone, we don't use them." He nodded in understanding and went back to his room. A little while later he comes back with an iPhone, charge cable attached, and says, "I can't get it to work..." It was adorable. I explained that I was talking about old phones, like the ones at his abuela's house. He said, "Oh." and of course immediately lost interest. You can see why I was reminded of it. It was, literally, an "unplugged phone mystery." I was half expecting to read a similar story. :-)
