If I find something that someone lost, I would try to find the owner and give it back. I think it's the right thing to do, and I hope someone would do the same for me. If I can't find the owner, I would give it to the lost and found.

If I can't find the owner, I would report it to the authorities or the management of the place where I found it. It's important to make sure the item gets back to the owner.

If I find something small and not important, I might leave it there, thinking the owner might come back. But if it's valuable, I would try to find the owner or report it.
