philosophy

I remember his hands hard as steel,
But never was I without a meal.
He was with me throughout my childhood,
His love was unconditional, and he always understood.

A strong love I thought we did share,
But why did he leave without a care?
When he left, I was devastated,,
And a lot of times quite aggravated.

My father gave up everything he had,
Sometimes I think he must have gone mad.
This all from a wonderful man,
In my heart I just don't understand.
