Keeping her safe entails protecting her from serious harm, yes? Not keeping her in a padded box. She will be safe, Marshal. She may encounter hardship, heartbreak, and even peril, but a deal such as the one you're making will give you the assurance that she will always come out the other end.

Now, if you imagined that a deal for her safety would entail her never having to brush up against hardship, heartbreak, or peril at all, and thereby missing out on an untold number of wonderful, worthwhile life experiences that can't be had without a bit of risk... then I'm afraid that you and I need to have a rather different conversation.
