Grief never really goes away. It lessens over time, receding into the shadows of your consciousness, but it will always be present. You can never let it go completely.
You might think that it can be tamed, this grief, but it cannot; it has burrowed and become a spirit inside of you, one that demands to be part of you for as long as you draw a breath. And you feel that this state of affairs is the correct one; after all, you don’t want to forget that which made you grieve. That would be a rejection of the life you had before grief came calling.
