Good morning , this is the second time I've read your post and you mention National Geographic. Last time, you helped a baby bird or baby birds (I can't quite remember) climb a wall. This time, you stayed out of it. It's funny that you mentioned National Geographic because that's how one of my upcoming publications ends.
Coincidences aside, I think I would have done the same thing. Not intervening and trying to take the photograph. The issue of my intervention is not so simple; if the lunch had been one of my new neighbours, I would have intervened.
What I am sure of is that we influence the course of history when we intervene and when we don't. There is also no room for doubt: you are a very good person.
I wish you sweet dreams.
