Probably of no importance, and if it is it's too late, but 'round and round' and valuable to you reminds me of a Zippo lighter I lost not long ago. It was very special to me, rare and expensive with a spiritual design on it.

Best I can figure it was on my nightstand which was next to a trash can (small dust bin). Trash is recycled (round and round). I unknowingly knocked it off the table and it fell in the trash can which was full I and threw it in the collection trash can which was duly picked up by the city.

I still miss it, dang it! Hope that wasn't the fate of your keys.

I trust Ia implicitly. If she says 'round' then I think that is key. Maybe it's with something you should get around to doing. Something you're procrastinating about.
