Things that come together and things that don't

Anatomies that come together.
Fleshy divisions that come 
together.
Writing instruments that come together.
World observers that touch
from far away.

Human feelings that go the opposite direction.
Smiley emotions, broken feelings, lost senses.

They come together, run the opposite way from themselves, they can't disappear from their perception, and crash on darkness that leaves red and sticky liquid behind.
