It's sobering to think of the day to day lives of the people in those situations, and how quickly anyone can find themselves in a bad way, with increasing prices, job security seeming to be a thing of the past, I can see it happening all too often to people who never ever thought they'd end up homeless. Being a renter, that reality sinks in even more -- we don't own land, a home ... we don't even own a tent (I've got it on my prep list though).
This is something I am learning quickly! Being there to loan money and time, etc, can lead us to sink quickly, it's hard to say no, esp. when there are kids involved who need 'help', but eventually it has to stop. It's still hard to do though, but when the result is being in dire straights ourselves, what alternative is there (other than sinking ourselves).
