What am I missing.

Let's not put counter-pressure on the gear with a stressed pin
The point has been driven home,
And it was time that conclusions were drawn
When walls crayoned with their words
Began to breathe, singing Home.
I checked the pulse against the clock,
I left my hands to try to stop it;
Cover your eyes, child.
You've already seen the train come in,
Come in, come in, the door is always unlocked,
So I took a step outside to taste a different air:
Used cigarettes and laughter,
Scrambled eggs and smoky hair.
Secondhand hints to the second hand's splinter,
Etching the light of a lesser known glimmer.
