What has she said that is untrue? She was very forthright in what might go through the minds of anyone who is near to, but not personally affected by a tragedy. A lovely shopping trip has been ruined and she now has items that are meaningless to her and also the sight of them will bring back horrific memories. I'm sure many of us have sights, places, fragrances, or other things we avoid because the evoke memories that are horrible. Isn't this what her point was?
Maybe it speaks to a flaw in my character, but I cannot find any empathy for her mis-speak. So her shopping trip was ruined, at least she is alive and not lying mangled in the middle of the street.
But that's just me, warts and all.
