IT OR I?

It? or I?
by Rainbow Joe

Let it plunder my soul,
even deplete me of my right to live,
but to steal my thunder?
No! it would not dare,
to have the gall.
The sun will shine,
and the moon will wane,
but to steal my nimbus?
Think again!
I will be here forever,
It may disapprove,
of my mien,
but it,
not I that must move!
