Never hazard taking part in a quadrille, unless you know how to dance tolerably; for if you are a novice, or but a little skilled, you would bring disorder into the midst of pleasure. Being once engaged to take part in a dance, if the figures are not familiar, be careful not to advance first. You can in this way govern your steps by those who go before you. Beware, also, of taking your place in a set of dancers more skillful than yourself. When an unpracticed dancer makes a mistake, we may apprize him of his error; but it would be very impolite to have the air of giving him a lesson.
