I invited strangers in without an issue, I wouldn't let me browse through my stuff but to escape the heat on a hot day while someone comes to fix their car I see no issue. I guess it all depends on where in the world you live, kids around my local neighborhood use my tools and air compressor all the time to fix their bikes, scooters and skateboards. To be allowed they have to get their parents to meet me first but I have a small shed with a simple tool kit for them. I have been allowing this for over 2 years now and have yet have anything go missing. IMO communities only become unsafe when people stop believing in them, but again, I guess its depends on where you come from. I am thankful to be Australian.
