Did it ever cross anyone's mind that some rings aren't "lost" at all, but are intentionally thrown away? Maybe as an act of letting go of bad memories or something like that, and that the previous owner doesn't want it back?
I was that way with my own class ring. Started dating this girl my senior year and that was "the thing" ya know, the girl wears the class ring of her boyfriend. The summer after graduating, I found her in the local school parking lot hangout, all over this other guy. I got my ring back from her and never wore it again. Every time I looked at it, she was all I could think of wearing it and I hated it. It's in my gun safe to this day. I told my parents one day that I wish they'd of talked me out of getting that stupid ring, and would have gotten me a rifle or pistol for graduation...because I guarantee it would have gotten more use over the last 20 years than that ring.
I know several people that during arguments, and or similar events, that they took their rings off and threw them out of frustration as far as they could and hoped they would never be found.
My first ever ring recovery was for a guy that my dad worked with....I think I was all of 10 or 11 years old in the fall of the year. Dad drove me over to the guys house, where the story was, his teenage daughter had been playing in leaf piles, and lost a ring in one of them. The story didn't add up to me, even at my young age. Why would a teenage girl be playing in leaf piles? Anyway....I got out there with the machine searching leaf piles and found the ring in like 10 minutes. The girl was not happy at all, which was also strange. Come to find out...her boyfriend had given her an engagement ring and the girl's daddy wasn't happy about it and did not approve. He told her to give it back...she refused and got mad, took the ring off and threw it into a leaf pile. I guess she thought he would have to pay the boy back or something like that. I find the ring and instead of being the hero of the day, I was public enemy #1. LOL
So I wonder some times, if when we recover a ring and then go all out trying to find the owner...if we shouldn't have just left it be. That could explain the attitude of some people when you do return one. Now days, I only respond to posts and word of mouth of locals that have lost a ring here or there. Social media has made this easy to do. I have already recovered 3 for people this way this year. Usually starts with "I know it's a long shot but...we were swimming at such and such lake and lost my wedding band...this is what it looks like...if anyone happens to find it, there is a reward". Those are the grateful ones.
