Do you find the world a kind place?
I get that it can be hard finding the kindness in the world, particularly during morning rush hour traffic, but really, the world is a kind place.
There was a study just recently done by Swiss university students where they left spare keys, wallets, and other necessary items lying around 355 cities across the world.
More often than not, the items were returned.
What was notable to me was that the larger the amount of money, or the more crucial the document found (eg passport) the more likely the item would be returned.
And there wasn't one particular city or place more (or less) likely than another to return the money. Across the board, we (as a species) try to do the right thing.
Now, if we (as a species) could just get the zipper merge worked out.
