Tell me

Tell me why the sky is blue.
Tell me why I loved you.
Tell me why you were so shy.
Tell me if I really tried,
to be the one you needed,
and if I treated you oh so bad.
Tell me why you left me,
Tell me why I'm sad,
Tell me why I miss you,
Tell me if it can be the same,
Tell me if you hate me,
Tell me if I should take the blame.
