No, it's not guilt. I mostly financially support my daughter and GS with my work, so I obviously have nothing to feel guilty about. If I didn't work, their lives would be very different to the way they are now. For most people work IS essential.
Yes, my flying does put me at risk. I'm aware of that. I do everything I can to reduce it, but it's still there. That is an essential risk though. No way around it. I don't take any other risks. And given my financial support, I don't think it's too much to at least socially distance (which she admitted she wasn't doing).
But yes. All OK for now. And I'm gone again soon, so the risks she takes after that are her business.
