Lightning Doesn’t Strike In The Same Place Twice
This saying most likely came about from somebody trying to convince themselves or others that they were safe during a lightning storm. When lightning didn’t strike the same spot twice, they probably took it as fact and decided to pass their newfound “knowledge” to others.
In reality, lightning can absolutely strike in the same spot twice, and it’s not even all that rare to happen. The Empire State Building in New York gets struck 20 to 25 times a year. On one occasion, it was hit eight times in just 24 minutes!
