Monday: Lightning creates a power surge, fries my computer at the office. Fortunately, data is stored on the network.
Tuesday: Lightning strikes a strip mall, destroying local businesses, including one of my clients. Firefighters can't fight the blaze because lightning could strike them (such as when on a ladder).
More than anything, I suppose, is respect the lightning.
