Magic box

I have this magic box. It has a picture of Papa's phone on it. It doesn't do much. My parents though insist it does.

They insist that Grandma wants to speak to me. Somehow, they keep hearing her voice on that box. Me, i don't hear much. Seems to me like they're yanking my chain. But its not nice to be rude when they insist as much.

So, I play along and appear to be totally taken by it and speak to Grandma at every given opportunity.

Now who's yanking whose chain? (snicker, snicker!)
