Sweetheart still knows that when 7:30 PM comes around that it is time for bed. She waits patiently on her top perch looking a little gloomy when the cover has not been placed around her cage on time. J. asks her, "Want to go to bed?" And she often gives him "the look" before ruffling her feathers, as if to say, "What do you think?" and sometimes even adds a chirp to show her enthusiasm for sleepy-time.
We turn down the lights, and turn down the volume on the TV (it is in the same room as her cage) but if we still are happening to be chatting about things -- she will rattle around in her cage, or chirp loudly in protest: "Keep it down, you two!"
I'm not sure about if/how her morning routine has changed -- it is J. who comes downstairs from our upstairs bedroom, to make sure the heaters are at a constant, comfortable temperature for Sweetheart, and to take off her night cover to prepare her for a new day.
