Unfortunately an honest person cannot return something if there is no way to find the owner. That is a great idea! I put a label on all my electronics so an honest person has no reason not to notify me.
When I was 18 I had just cashed my paycheck ($130.00) 1970s. I stopped at a payphone (no cellphones). An hr later I realized I left my wallet. I went back to the pay phone and it was gone. I was sick!
When I came home several hrs later my mother said a man came by with my wallet. He appologized for not coming sooner but said he did not live in the area and it took him awhile to find where we lived. This was in Huntington Beach CA. My mom offered him a reward and he refused. He said he felt an 18 yo needed it more than he did. I was so excited I did the happy dance!
