Why did I become a woman?
Because an extremely unlikely quantum mechanical event caused me to randomly turn into one. A physicist later described it to me like this: whenever you shuffle a deck of cards the odds of you getting the order of cards you end up with is approximately 1 to 80 × 10⁶⁶ (The Factorial of 52). You beat odds greater than the number of molecules in the Milky Way Galaxy every time you play a round of Crazy Eights. While randomly turning into a woman was highly improbable it'd be even more improbable for weird stuff like that to never happen.
