a tails and a head

I could never find the right words
But lost in yours
I listen and hear the deal
I equal out the value and find the real
So confused you’re not sure which way to go
I add some change
You subtract some more
Who would have known that these math problems fit in so well?
When I sit back and listen
I’m here and you are right there
So please stop begging and telling me you’re not the same
When a nickel gets flipped
Its sometimes ends in the same
Face down in the dirt or tail dragging along
Which way will you chance go
Not formed of seven sides
Just two
A tails and a head
So figure my equation
When I added gravity
