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!
They say that you get used to everything. This is true, but still we miss our Dandy. We phone to the refugee center regularly to ask about our Dandy, and the answers are always the same: Dandy is still in quarantine but fine, he has adjusted well, he has stopped picking his feathers, he is between other Greys, although still in the same cage on his own. We are not allowed to visit him yet, but we will, as soon as his quarantine period is over!
