I had a quiet miracle happen to me this week. I lost my keys when I stumbled and fell walking home from a site a few days ago. I searched the area where I thought they might have fallen three or four times in vain. I finally gave up looking.
Two days later I had the distinct impression I should try looking one more time. So I walked back down to the area. When I got near the place where I fell, I realized how impossible it was to find a tiny set of car keys that flew out of my purse into a big field.
