No matter where we go, we're likely to come across something strange if we see enough of the world. Since we're usually focused on our own business, these chance finds can be pretty easy to miss, but we might discover that some things are unusual enough to steal our focus for a second.
And that second is all it takes to make us curious. Did someone drop this or did they leave it here on purpose? Do we actually want it or do we feel compelled to leave it behind?
And sometimes, the biggest question of all is the simplest: What is this?
But while we may never know the answers to all of our questions about this stuff, we can definitely see why someone needed to share them with the world.
