Subject: Thinking of you

Dear [Name],

I was very sorry to hear about [situation, in the family's words if known].

I won't write much. I just wanted you to know we're thinking of you, and to say that whatever space you need, we'll make.

If there's anything practical I can take off your plate — meetings to defer, calls to hold — please send me one line and I'll handle it without you needing to think about it again.

Please don't feel any need to reply.

With kind thoughts,
[Your name]
