It's not unknown that sometimes uttering the word YES is as hard to decide as riding a Ferris wheel for the first time. It's like running excitedly toward the ticket booth and instantly feeling anxious because it will be your first time. Then you're struggling in buying a ticket pass. You may even be considering constantly standing aside and watching the bright smiles, waves of laughter, and even the screams of excitement brought to the people who dare to ride it.
