Never has a well struck primer ever failed. Ever. It was clearly Divine Intervention, you were spared because you have a greater purpose that you have not yet completed. Jump in front of a bus next week to prove it, you're untouchable until you complete your Divine Assignment. But after that, you better watch your back, Jack.

Seriously though, it happens. Luckily for you, it coincidentally happened right at a moment that turned out to be incredibly fortuitous for you.
