I was trying to explain wireless technology to my seven-year-old son Adam. I said, "It's like radio." He said, "What do you mean, that's plugged in." I told him that was only for power, and that the signals were picked up from the air. "In fact," I said, "the air all around us is filled with songs, talk radio, TV shows. If we had TV antennaes growing from our heads and TV receivers in our skulls, we could walk around looking at TV shows without any TV."
Man, some days I freak myself right out.
