How do I eavesdrop on mo and elinor?

Go to the library door, press the A button, it will highlight twice by the latch and on the hinge. Take note of what Meggie says. Go back upstairs to her bedroom - pick up the ruler off the desk under the window. Go back downstairs,(press A button to highlight kitchen door.) Go into the kitchen - there is a bottle of olive oil on the table but the little horned creature is just by it - go the the fridge and get a piece of salami and throw it out of the kitchen door for it to get it. Then go to the table and pick up the oil. Go back to the library - lift the latch with the ruler and oil the hinges with the oil!! - then hear Mo and Elinor.
