Subtle Variations

Inevitable said to Preordained:
beg pardon, but we're not the same at all.
Though this may color our relations strained,
you prophesy, preparing for the fall,
where's I am more so focused on effect,
the cause but an assumption in my work,
whose output is about as you'd expect,
and worthy of an understanding smirk,
that, rather than a shaking, angry fist.

Here Preordained objected with this point:
(in truth she could have given a whole list)
Inevitable, your nose out of joint.
Our means may differ, but our goals the same.
Attempt, when something happens, to lay blame.
