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.
