Who are you?

Who are you
Who am I?
If you're good
Am I bad?
If you're happy
Am I sad?
If water is clear
Why is the sky blue?
If I tell lies
How do I know what's true?
If the moon is dark
And the sun is light,
If what I am shatters
Will you make the pieces unite?
If you're strong
And I am weak.
If you're exciting
them I am bleak.
If time can stand still
Would you make it rewind?
If I held the remote
Would you mind?
