I'm sorry for the lack of clarity. I intended no sarcasm. For me the loss of significant data has been/would be a real loss. "Mourning" usually implies the loss of a loved one or friend, but I've used it here to refer to the extended emotional disturbance in the wake of losing something important. I certainly would not be able come away unshaken from the kind of incident you describe.

Again, my regrets over your loss of data.
