Life? Poem by Victoria Black

Life,
What is life,
Is it the cats stride as it runs down the street?
Or is it the soft pur when you pet its fluffy coat?
What is life?
Is it the swaying of a tree in the wind?
Or is it the birds singing in the tree on a bright spring morrning?
What is life?
Is it that thrill that you get from watching a horor movie?
Or is it the aftershock of being scared for your life?
Life,
What is life?
I wish someone could answer my question.
