The Silent Language Book

16 - good story of cross-cultural confusion
17- cultures have an appropriate "lead time" - how much advance notice you must give about something to plan ahead.
35 - there are no basic, elemental units for culture and therefore it is impossible to teach culture the way you teach language. Some of this is because culture is a deep, unconscious thing.
39 - "culture hides much more than it reveals, and strangely enough what it hides, it hides most effectively from its own participants. Years of study have convinced me that the real job is not to understand foreign culture, but to understand our own."
53 - learning how to learn is an assumed cultural value. In other words, a national might not grasp something because it has been taught in a way that doesn't fit the way he learned to learn as a child.
58 - Americans tend to compartmentalize religious, making it a thing that only affects part of your life, while other cultures regard many things as essentially religious.
69-72 - there are three kinds of learning OT cultural knowledge: formal (hours, days), informal (later, a little bit ago), and technical (picoseconds, millennia). Formal is learned as someone corrects you for making mistakes or breaking the rules. Informal happens as you involuntarily "pick things up." Technical comes from a teacher or textbook - cold, hard facts.
74 - the informal tends to be automatic and assumed, making it an area for cross-cultural problems.
