In the theatre, as a rule, the texts that can be read, the actors do not teach by the mouth, but simply read from the sheet. I did not remember what the spectacle was, but the point is that in the course of the stage, a man runs into the scene and passes a letter to the king with the words:
Your Majesty, a letter to you!
The King unfolds the scroll and... Oh, horror, there is no text (colleagues joke). But he was an experienced artist and, returning the scroll to the racer, says:
Read the race!
The artist who plays the role of a gunner, too, was not a lick of sheets, returns a letter to the king:
You are not literate, Your Majesty!
