Poor Mal, and poor Tsubu... But you know Tsubu, bird always fly away if they can even if they love you, and there is some dogs like that, so it's not your fault, I'm sure that you were very kind with him. I had a bird who felt down of his nest once, I took care of him, and when he was an adulte I goes outside with him he fly away go back on my hand few minutes, and fly again with no return. Because he came back I tought he really love me but he was gone anyway...
Thinking of the real Miku scratching the keybord is.......... interessant........and cute!
