"There's nothing wrong with pushing a few buttons but just expressing your view can also be a warning, just in case. "

I'm not sure I understand this last part.

One thing I have not managed to tell him, and don't know if I should, is that I would do the whole thing over, exactly the same, if I had the chance, since I know it turned out all right. Of course, the saying goes "you can't step in the same stream twice" so perhaps it's better not to try repeat things exactly, especially ones with so many things coming together by happenstance. Anyway, he said he'd make sure to do the rope differently next time.
