There are question marks all around us, and if you've ever had a toddler in your house, you've probably been made aware of roughly 1,000 that had never even occurred to you. The vast majority of us will, at some point in our lives, either drop the questions, or direct them down a particular path.
But the questions are still there - we might just not realize that we haven't asked them. And it might not even occur to us to ask them until they've already been answered!
