Hoi, hoi, hoi. I noticed that I can use it as a contact call: every time when Sophia leaves the room, I say it. It is guaranteed to get a hoi back. Every time again!
I had a major panic attack! Jan and Sophia continued where they left off yesterday: they took me in the car again, closed the door (gently) and Jan started the car. Boy, was I scared. I tried to fly through the car window, to the back seat and on the front mirror. Finally, I crept under Sophia's arm and stayed there, panting. I hate the car. It messes up all my feathers.
