I promised san I would not try to jump out into the corridor. I have not been near the door grilled ever since she scolded me. But san said cats are notoriously forgetful and once we learn something it is difficult to unlearn it. So we will be getting a new set soon. So for now the door is always closed and none of us can look out of the door until the new set of grilles are fixed. Sorry san and sky and Manju.
