It's true, grief never ends.

Right now, I'm watching Harry Potter and the Goblet of Fire.  There's a scene towards the end where Cedric Diggery's father cries over his son's dead body, and I nearly broke down.  It's very hard for me to watch movies where a parent grieves over the loss of their child(ren) - for me, the pain is all too real.  It was years before I could watch Jackson's The Two Towers, because of Bernard Hill's (adlibbed) line "No parent should have to bury their child."

Time does not heal all wounds, let no one tell you that.  Time may teach you how to live with an open wound, but it never heals.
