I think I can see molecules

I see the ending
i see the truth
I see the way that happiness
parts form us
and makes people move

I see the wonders
I see the fear
I see the way that people run
from the things that bring them tears

Its a weird sounding
heart compunding
letter that I wrote
It's a nervous little speech
its a small little choke

Its one for peace
its two for war
its the third one and hes at my door
its the ancient people screaming out
its a drill Sargent learning to shout
It's molecules
