Role's game

- What's your favorite game?

- Guard and thief.

- What role do you like to play in the game?

- The thief.

- It's because you feel guilty?

- Because I like to be chased.

- And when you get caught?

- It never happens.

- Why?

- Because before the guard can do it 

I'm already gone.

- Run fast, then.

- Enough.

- And in prison who goes there?

- The guard.

- Why?

- Because he has failed to catch me.

Only for this?

- No: especially for attempting to do so.

- Wasn't it his role?

- Yes.

- But?

- He lacked the motivation to do it.

- And who might had provide it?

- A judge.

- But that role is not foreseen in the game!

- That's why the thief was gone.

- And when he came back?

- He judged himself.
