Yeah, when I had a book study at my house I would notice things missing after everyone left.
I had a close friend, a disabled brother, who told me this story that happened to him. He had gone shopping in Walmart and used one of their scooter/wheelchair things. He was able to stand and take a few steps, but he couldn't walk and carry things at the same time. Someone had driven him to the store. Well when he went thru the checkout line he stood up to pay. Then when he sat down in the scooter he put his wallet in the basket rather than in his pocket. Then he got into the other person's car, along with his items, but left his wallet behind.
It wasn't till he got home and his ride had left that he realized he had left his wallet behind. He called the store; they said it had not been turned in but they would call him if it did appear. But then someone came to his door. It was "worldly" people who had found the wallet. They had just come thru the checkout line, saw the wallet and reasoned that a disabled person had left it. So they looked inside for ID and immediately went to his home with it, to return it, on their way home from the store. Everything was intact. The brother was relived, of course
There are plenty of honest "worldly" people out. Not all of them are demon possesed immoral criminals, as the WT tries to scare members into believing.
