@568cb1e6 There is an amazing variance even amongst cultures. I've been watching Korean drama recently, and they have a completely unique half-smile Americans to convey a nuance we never do. Learning Japanese, I've gotten a book on gestures you need to learn to be fully understood speaking there. In one of my stories, the aliens gesture with facial feathers and can't make certain human sounds, so the humans learn their language and use their fingers held near their cheeks to speak "alien", which I modeled after Bahasa Indonesian (another language, a pidgin originally trading language, I partially learned when I lived there for awhile).
