Whenever thunder grumbles overhead, I think of where I am. Am I indoors, outdoors? Am I standing in a safe place? Can we get to the car? Is everything switched off at the plug?
Then I find an appropriate window to watch from.
Then I think about how it works. How does the lightning know what to strike? Is it striking everywhere, all through the storm, but only completes the circuit when it finds something that will take it all the way down to earth?
Then the lightning strikes.
Then I think, wow.
