Was randomly looking up interesting facts about Japan in preparation for the move in September. Here's one that's kinda ....sad?
Not only is it considered rude to blow your nose in public, but it is also considered rude to openly express your emotions in public. This is why a straight face showing absolutely no emotions is worn by most of the people in Japan. It is also unheard of to show any signs of affection in public.
Note to self: keep booger intact. No hugging. godammit...no hugging.
