Inside the house is the best.
        Maybe it's not true. But I don't have to face to anyone else as long as I'm in the room.
        
        I'm conciderate. So I can tell inside and outside apart.
        On the other hand, anyone who are impudent behave in the same way that they do inside their house.
        That's why out side is so polluted by them.

        They never tell what they may do and may not do.
        But still I don't know why they do so...

        The mistery is remaining to be contemplated as ever.
        Note that it's 'to be contemplated' but not 'to be solved'.
        That's a huge deference.
        It's not likely to be solved no matter what as you know.
        Even so I must stick there.
        Otherwise the meaning of life would disappear.
