I think grief is a huge subject; it's one of the things that everybody is going to confront in one way or another. There's been a lot of books written about how Americans have an odd way of trying to defer grief or minimize the need to grieve. People used to have a lot more ritual grief in their lives. For the most part, we think of it as a strictly temporal process: you grieve for a time and then you're over [it], but it's also a spatial process. It travels across a map.
