There's A Side To You That I Never Knew...

Eye see corruption in thine I
you have strayed far from the path
which i set out yet i do not protest
too much for that your right
high up in your elephantine tower
is it not a long way down
Oh? doth thou protest too much?
Shakespeare says he thinks it
I do not condemn for I have passed
it is my time no longer
One day I shall sail west
join my children in the Grey
