When I was little, I was out riding my brand-new blue bicycle when I decided to see how far I could keep going without looking back even once. I could feel with my back how my neighborhood was receding, further and further away... but I kept pedaling with all my might, my mind almost going blank. All I could hear was the sound of my own heart, thumping wildly in my ears. Even now, I remember it sometimes. What exactly was I trying to do that day? What was it that I wanted to prove? It's no good. My mind just keeps fogging over. I have this irritating sound stuck in my head. What is it? This sound... Ohh... I know what it is. This is... the sound of emptiness.
