question: When Miss Millie purchased her new parrot, the salesman assured her that it would repeat any word it heard.  About a week later, Miss Millie returned the parrot complaining it hadn't uttered a single word.     Given that the salesman had spoken the truth about the parrot's abilities, why wouldn't the bird talk?
