The Talking Bird

A man was eager to buy a talking mynah bird for a pet. And, was delighted when the local pet store had one on sale.
“Is it smart?” asked the man. “Will it talk?”
“I guarantee this bird will repeat every word it hears,” promised the woman at the store. “Or you’ll get your money back.”
A week later the man went back to the pet store in a furious mood.
“You promised me this bird would talk. But I’ve been trying to teach it all day every day for a week, and it still won’t say a single word. I want my money back.”
“Sorry.” said the sales woman. “No refunds on your bird. Every word I said was true. My guarantee stands.”

What’s the truth, the whole truth. And where’s the lie?

The exact words the woman said were true. When she promised the bird would “repeat every word it hears” she didn’t say the bird would speak. In the whole truth, the bird was deaf so it never heard any words to repeat!
