Idk maybe it's cultural thing but why are Japanese can't say what they have in their mind, they always warp their words nicely but it's not an honest words, they won't get to the point, I mean like they're too conservative they're too afraid to hurt other people with their word and because of that they will hurt other people more.
Sorry if I'm generalizing Japanese but most of my Jap friends is like that, there are some exception...but yeah most of them is like that, it becomes obvious when they speak the truth or just when they sugar coating their words.
