It's very attached to him !!!

Eddie	I'm sorry that the parrot is squawking its head off.
Denise	What's the matter with it ?
Eddie	Well it's just spotted a cat outside the window and it really doesn't like cats.
Denise	Do you ever let it out of its cage ?
Eddie	My father does. It's very attached to him so it perches on his shoulder and behaves itself when he's around.
Denise	Would you ever let it out ?
Eddie	Oh no, because it's more than likely to give me a nasty nip if I do.
