I think I have come up with almost the perfect response to these well-meaning inquiries:
She's doing about as well as can be expected, under the circumstances. But she misses her friends, going to matches, spending time on the range, and shooting.
She wanders around the house muttering "I've got to shoot something."
I assume she means targets, but in any case I'm safe. I robbed all of her .38 Super ammunition months ago so I could shoot matches.
She has lots of .38 Special ammunition left, but I'm still safe; those are reserved for her Home Defense guns. She's too proud to shoot Revolver under any but the most dire situation.
