Blue is the color of sadness. Also the color of hope. Rain is blue. The sky is blue. Clean water is blue. The TARDIS is blue. Most consider this color sad, but if you can truly see hope, you can see that blue is closely associated with it. If given blue water, the children of Africa would rejoice. If they were graced with even a few minutes of rain, they would cry tears of joy.
For those who live with clean water, after a thunderstorm or particularly bad event, we look for the blue sky. We search for the hope that comes after the fall. For the little square of blue at the top of the well. We search for something to take us away from the bad times.
The TARDIS. The hope of everyone who sees it. Some search their whole lives for it, some see it once and never forget, some never even know it saved them. He saved them. The hope of all the worlds contained within a small blue box.
You can imagine my joy and my hope when I first saw the box. I was terrified, but the sight of the box gave me hope, comforted me. I saw the man inside the box, and he smiled at me. My world was falling apart, but his smile cured me of my fright. His old eyes stared into mine. In them I saw the fall of many a world. And I saw that he would not let the same happen to me. He held out a hand to me. He came to save me. My world was burning, but this man was my anchor. My savior. My hero. I ran to him, but the ground began to shake below me. I was forced to stop. My legs fell from beneath me, but before I could hit the ground, strong arms encircled me. He lifted me up and carried me to his blue box. My hero had saved me. Of all the inhabitants of the planet, he had been in the right place at the right time to save me. Lowly little me.
"Why?" I croaked, through the smoke filling my lungs. His smile was blinding and all too cheery in a dying world.
"Because," he said, looking down into my eyes, "In 900 years of time and space, I've never met anyone who wasn't important."
