About a week ago, I decided to start playing peekaboo with Einstein.
He took to it right away. He opens his wings up, and he just gets the happiest look on his face.
I cover his face with my hands, and when he's ready for me to move my hands, he touches them. I then lift up my hands, and he yells "PEE!"
He's even started trying to hide behind my hands when we're not playing.
He's such a clever little tiel, just thought I'd share.
