I don't know how I managed to miss this lovely story till now. Thank you, dear
DSR, for doing Beth such justice. As you might know, I'm kinda partial to Beth...

and I could
believe in her here. You drew her in a way that made perfect sense.
Josh's death was obviously a horrible blow to her--both to her heart, and to her conscience. She had to mourn not only the loss of this man who had loved her so truly and faithfully, but also the loss of
her faithfulness to
him. Guilt makes it hard to move on. It drags us back, makes us play "what if" games. I can easily imagine Beth spending a week processing these feelings, going through the motions of dealing with Josh's effects, signing paperwork, making arrangements... and going around and around in her head, wishing things had been different.
But Beth's not a brooder; she's a person who copes and moves on. And the funeral would be the perfect day for her to choose to move on from her ties to the past, embracing what (and who) the future held. Human Mick's wounds are visible, and Beth's are hidden below the surface, but they're both battered here. I imagine her looking at Mick during that service, hearing those words, and making a private vow to seize that day with both hands.
This is one of those stories that have fascinating comments--I enjoyed reading them so much. They added to my appreciation of the story, and I agree with so many of them. This is obviously a story that touched many hearts and provoked many deep insights from the brilliant readers here.
