Fidelius Uncharmed

The Fidelius charm is theoretically sound. It operates under the theory that:
"The spread of your secret (and its standard deviation from the truth) is proportional to the square of the number of people who know your secret."
Unfortunately, math masks the real issue: The more you trust a single person with yourself, the more you are likely to be hurt if they walk away. Even if it is only for the one minute that you really want them around.

I'm back to Guns-'n'-Roses. At least, I love my job this time around.
