The people who knew her say she cooked with a vengeance.
Now her ghost, or spirit if you will, is still in the kitchen.
Did she consider herself a slave to the task?
Could she have actually been taking revenge on the food?
Why did she feel it was important enough to continue after death?
How do you convince her to rest?
Will she haunt this kitchen eternally?
She claimed her husband was a slave to the cattle herd.
If that was believed then revenge on the food is possible.
Though the mimicking of cooking is done, nothing is really cooked, anymore.
Her task will never be complete.
There will always be a need to cook, for as long as people eat.
Can she rest as long as that need exists?
