For clarification, it's not real.

When you write a petition you need to start by typing a period (.)
Then you need to type the answer to the question that Peter
supposes to answer.   On the screen, it will appear as:
“Peter, please answer my question:”.

In order to see the full sentence, continue pressing
on the space bar, and at the end press 'Enter'.

On the question filed, continue by asking a question
to the answer which you already secretly put in.

Now peter knows the answer, that’s it!
