I lost my keys a few days ago. I had let my 5-year-old have the keys to open the front door when we got home. A bit later I'd brought in some bags of animal food from the car. The next day I went to take the kids somewhere and... no keys. The tricky part was that we weren't sure who had last had the keys. Was it the 5-year-old? Or me? I didn't remember if I'd left the car open, and so didn't need the keys when I went to get the food from the car (and thus the 5-year-old was the last to have them), or whether I'd locked it, in which case I would have needed the keys. Looked everywhere. It was getting pretty bad. I thought at first that it was pretty silly to pray to find my keys, but I got over that and did pray. About 5 minutes later I found them. Where? In my shoe!
As near as we can put things together, we *think* that the 5-year-old left the keys somewhere obvious. The 2-year-old, who loves keys, found them. That evening at one point she was pretending to be "mommy" by walking around in my shoes, and she possibly had been carrying the keys at that point without my noticing. She must have then put them in the shoe. Problem solved.
Part of why I was nervous was that the keys included the difficult-to-replace car fob, and because I lost my keys once before and never found them. I'd gone to a Bible study at somebody's house, driving there. Went in, put my purse under my chair. Went to leave... no keys in purse. Not in pocket, not under the chair. Not in the car, or on the ground between the car and the house. Just gone. They were even on a red lanyard, which you'd think would stand out. They were never found, not by me and not by the people who lived in the house, not even when they moved to a new house two years later! Now *that's* a mystery I'd like to know the solution to!
