It's fuzzy. Like a sea urchin.

Because a happy goodbye
is a goodbye nonetheless.

Open your eyes,
remember this moment,
for this is life
and not a dream.

Suppose that a) you are a mathematician and b) someone is firing a bullet toward you. Your first instinct might be to perform a geometric inversion on a sphere surrounding you but not encapsulating the bullet. This might seem like a good idea; no bullet, no death. However, you have deceived yourself. By performing a geometric inversion on this sphere, you have only left yourself with a (relatively) minute amount of oxygen available for your use. You have also left the human race behind. Change is indefinitely present. We are not.

The wheels keep turning, even though there's no one there to turn them.
