Good point--I like the idea of expressing that I've been keeping her in my thoughts without asking any questions. 'Cause asking "are you all right" is almost certainly going to result in some demurring + redirecting combo (e.g. "things have been okay/difficult/whatever; it's kind of you to ask. I'd like to hear about how *you're* doing, though."). And asking for actual info feels intrusive.

This is one of the many reasons I really appreciate PC--y'all have solidly helpful perspectives on these things
