THINGS I UNDERSTAND BUT DON'T ACTUALLY BELIEVE SHOULD WORK

No, honey, you don't need to explain radio waves to me again
  1. Radio
    Music just floats through the air and then into my ears?
  2. Airplanes
    People act like flying is normal but it's NOT
  3. Freeway overpasses
    You shouldn't drive in the air even if it is more efficient and saves space or whatever
  4. The post office
    Every time I mail something I think, "there's no way this will work." How can they keep track of so many little pieces of paper when I lose my water bill every month?
