> For example, sometimes you'll be saying something in English to a Japanese person. They have no idea what you're saying, but because they're such good listeners, they're saying "yes, yes, yes" to everything you say (because that's the translation of hai, right?). At some point, you ask them an important question: "Do you want to join my Starcraft2 team?" They say "yes" not because they want to join your team (they really don't) but because they have no clue what you're saying (and they're good listeners).
That explains a lot honestly
