There is some leeway with parrots, their behaviour can be more obnoxious if they are stressed, or if the bird becomes mate bonded to the owner. That said, they all make noise, and some species are just really ear piercing loud anyway. Regardless of who pays for the bird's care and does the work to care for it, everyone sharing a household with a parrot has to put up that parrot. The girl's father HAD said, "No." She shrugged it off because he had said "No" to the last bird she bought.
Times have changed, apparently, but I thought her attitude and intended course of action was inappropriate.
