Honestly I think lesson 7 is nobody's normal. All the things the author's noted about interacting with other people - see how weird and rare it was and how long it took to recognize it? See how often it's on your plate to be the one to go zen mode to figure out how to dance with someone? The author isn't normal, they're now skilled. Before, they weren't normal, because they noticed they weren't skilled. Most people don't.
