Because
Just because I smile and smile
And happiness is not my coat
And my song tuneful and strong
Though you send me down below
Into unlievable regions
Of the blue rocks of the earth
You think then I am a gatepost
Numb to the stab of pain
Just because of the laugh of my lips
And my eyes covered in respect
Pants rolled up above the knees
And my dark hair all down dun-coloured
And thick with the road side dust,
My hands swinging a pick
And the back stripped out of my shirt.
You think I'm like a stone
And don't know what it is to die
Because at the fall of dark
When I've loosened the chains
Of my long day's labour
And I fall in with my brother,
Stamping the ground in a tribal dance
And we sing songs of old times
That stir up our fighting blood
Driving away all our cares
For that you think I'm a beast
That breeds its kind and dies
Because I seem to you simpleton
Knocked over by plain ignorance
And laws beyond my understanding
Except may be you rob me
And the house built for myself
Under the hand of a rock
A hut of grass for my home
My clothing an empty sack
You think I'm just an ant heap
And not one tear have I in me
To drip out from my own heart
And run over the pure hands
Of souls who see all.
