Gravity

It seems to me, that gravity 
Holds birds and bees, trees and leaves
Near the ground, without a sound
It can’t be found, but we are bound

Bound to the places, our bases 
Real spaces and human faces 
The power that grips the ships 
And flips the drips

A force of sorts
Without remorse or changing course 
Joins tight day and night 
All in sight but light 

Known but never shown 
A bone you don’t own 
A heart flown but not sewn 
A clone all alone
