Answer:

The whole premise is incorrect: That's just a SAYING about lightning never striking twice in the same place. Of course it's not true. Otherwise, why would anyone have lightning rods?
I think the statement refers to striking twice in a row or within the same storm formation.
Lightning can strike the same spot twice. The pole on the Empire States Building is hit more than twenty time a year. Lightning is nessicery for putting nitrogen back into the soil so if is ever stopped storming crops would no longer grow.
The more suitable proxies you adult males positioned on the following the more suitable they receives blocked. in case your stuck you receives suspended and your parents receives a telephone call from the police officials do your artwork and recognize the regulations.
The statement has little to actually do with lightning, especially these days. It really applies to human nature and events. Before the advent of tall buildings and lightning rods, it was rare for lightning to strike the same location twice; there were many likely targets. While it could happen, it was outside the daily experience of most people, and back then, that's about all they had to work with. The statement came to mean any event that rarely happened twice to the same person or group; like a previous poster said, winning the lottery twice, or any other event that's rare enough the first time, and extremely unlikely the second.
