There exist in this sometimes sad world, moments that remind you that you are alive.
You know these moments well. Blood rushes from your toes to your cheeks. Or from your cheeks to your toes. Either way you are made aware of its movement.
A great energy is felt in your jaw and in the ends of each strand of hair. Your fingers curl. Your hands turn into fists or claws. Everything is hot. You shudder violently (the energy must be flung off or you will be eaten alive).
