The most terrifying thing for a child is when you have a neutral facial expression, that they can't get you to react. If i just start smiling, lake, hey, how's everybody? Your doing today? There's something about that that could be comforting. And the second that my affect changes, now my affect has changed, like and so all it takes is fluctuation of affect. So if you like, go to a child, don't do this to children.
