On my virgin voyage to Tokyo, I was riding a train during rush hour as recommended by some friends,then I saw this demure Japanese lady flew a little smile towards her then offered her my seat. She refused politely in English (a surprise since not many people speaks English there) then she asked me why am I so kind since no one ever offer her the seat on the train during rush hour. I said, perhaps its Balinese hospitality? The world is too strange already, lets break it with a little smile..
