Thanks, this actually explains a lot. Korean is like this too. I'm realizing that a lot of communication difficultly comes from my aging mother speaking more slowly with words coming out this way. I get impatient thinking 'what are you talking about? get to the point' and frustrated if it takes very long or if I'm already busy or in a rush. It's like watching a movie with no context and an extended set up--not great if you weren't expecting the pace.
It definitely does extend beyond sentence structure. There will be preamble that sets the stage and covers considered adjacent points, then finally get to the ask/point.
