Today I've been thinking about conversation customs, thanks to the teapot storm of "Paris' Olympics' opening ceremony".
It's well-known that anglo-americans are the worst actors in any international setting, as they've least experience on working with people from other cultures.
As such they're more likely to (1.) not context-proof their messages against other interpretations AND (2.) not checking if their interpretation of an event is the one intentended.
