I once watched a roofer working on a house next door to me diligently trying to get the felt down before the storm started. I suggested he should get the hell off the roof but he basically said, "I don't want to have to come back tomorrow." (Paraphrasing). At the time the lightning strikes were between 1 and 2 miles out. He worked through the storm until he was done. I watched the whole time as lightining was literally striking within 500 feet of us and he never flinched.
Idiot.
