Grief: a Long Valley
This is the fourth--and the last--empty MS book I can find in the house; at least nearly empty, for there are some pages of very ancient arithmetic at the end by J. I resolve to let this limit my jottings. I will not start buying books for the purpose. In so far as this record was a defence against total collapse, a safety-valve, it has done some good. The other end I had in view turns out to have been based on a misunderstanding. I thought I could describe a state; make a map of sorrow. Sorrow, however, turns out to be not a state but a process. It needs not a map but a history, and if I don't stop writing that history at some quite arbitrary point, there's no reason why I should never stop. There is something new to be chronicled every day. Grief is like a long valley, a winding valley where any bend may reveal a totally new landscape. As I've already noted, not every bend does. Sometimes the surprise is the opposite one; you are presented with exactly the same sort of country you thought you had left behind miles ago. That is when you wonder whether the valley isn't a circular trench. But it isn't. There are partial recurrences, but the sequence doesn't repeat.
~C.S. Lewis, A Grief Observed, Chapter 4 (1961)
