mind one's p's and q's
Practice good manners, be precise and careful in one's behavior and speech, as in Their grandmother often told the children to mind their p's and q's. The origin of this expression, first recorded in 1779, is disputed.

mind one's p's and q's, to
To be very particular about one’s words and/or behavior. The original meaning of p and q has been lost, and there are various theories, ranging from “pints and quarts” in the bartender’s accounts, to children confusing the two letters in learning their alphabet, to the French dancing master’s pieds and queues, figures that must be accurately performed. The term was used from the seventeenth century on but is heard less often today.
