You are sitting in your room talking to your friend on the phone when suddenly you start hearing every word you say repeated. You look around to see who is mocking you but can see no one around. You return to the phone to talk some more and again hear every word you say repeated. You think it is coming from your window. You walk over to the window.
"Hello?" you say.
You see a bird sitting on the tree outside your window open it's beak.
"Hello?" the bird repeats.
"Stop that!" you yell at the bird.
"Stop that!" the bird yells back.
Gosh that's annoying! You must shut this bird up. But how?
