I wonder if the friends she is staying with also highly recommend that mode of living.
I suspect Ann is moral enough to know that she can't freeload- at least not forever. Perhaps she is doing the housecleaning, house maintenance, babysitting, shopping, or other tasks that her Hosts need done. If so, she is merely engaging in the sort of Barter economy that we will all be forced to-- probably in pretty short order if the COMEX crash is really as imminent as some predict.
In the coming days of turmoil our best laid plans may go awry- Maybe Colorado will become such a War zone that neither place I own is safe for my family. I may end up imposing upon friends elsewhere for a place to be, but I would know my duty would be to repay such kindness in any and all ways available to me. Likewise, I have other friends, prepped and un-prepped, who may find their plans stymied, unable to safely travel to their bugout, short on supplies, or simply in need of help who may seek refuge under the wings of my abode. And I would expect the same of them. No free person likes being beholden to another, for they know they are placed under obligation and debt, and therefore control.
