When we leave in the morning for work, we close the bathroom door and both bedroom doors. Ella has started running under me/hubby's bed in the morning when she knows we are getting ready to leave. This way we can't close the door, and she will get to sleep on the bed while we are gone. Our bed has low clearance to the floor (and she is now an expert at swishing under it) and it is horrible to try and grab her out from underneath the bed. Well we learned to take her outside for her morning potty walk, and just close the door then.
Well now she will do this every time she sees us get ready to leave the house, on those times when she doesn't get to ride along.
So we have started calling the dash under the bed, "Ella's goodbye".
