Yes, I think humans must be pretty scary to lots of animals!
I think it may have been someone else who said something about torches. Shining them at hogs should not be encouraged and should only be used in an emergency if a hog needs rescuing for some reason. It is probably not so much that the hog wasn’t bothered by it, than it was dazzled by it.
Glad to hear you have a new hog there. It can be quite amusing watching their antics. Probably the best way to watch them is to have an area that is lit, so that they can choose to go into that area or not. Then they will often provide lots of entertainment, what with biffing sessions, courtship circling, etc. I feed near to the house, so that I can see them out of the window, with the room I am in being dark, so they can’t see me and I don’t interfere with any of their interactions. Even so, they often ‘appear’ to be looking at me with those lovely shiny eyes.
