That is a bit of an uplifting story.
What a happy experience.
I ran into a person on a commuter train who I got to know over a 9-year period. And we had fairly similar backgrounds, but when he was in high school one summer in North or South Dakota where he lived he lost his high school ring one summer day waterskiing.
So 40 years later he came on the train and he flashes this HS ring and it was HIS high school rinn! Somebody had found the ring in that paticular lake decades later and they were able to track it down through the initials on the ring at the high school etc...
