Do you Listen

I know you look,
but do you see?
I know you hear,
But do you listen?

I know your here,
But are you there?
I know you cry,
But are you scared?

I know you lived,
But are you alive?
I know you trust,
But do you care?

I know you read,
But do you comprehend?
I know you noticed,
But do you know how it began?
