Well, what is the price of lettuces? An obolus perhaps. If, then, a man gives up the obolus, and receives the lettuces, and if you do not give up the obolus and do not obtain the lettuces, do not suppose that you receive less than he who has got the lettuces; for as he has the lettuces, so you have the obolus which you did not give. In the same way, then, in the other matter also you have not been invited to a man's feast, for you did not give to the host the price at which the supper is sold; but he sells it for praise (flattery), he sells it for person attention. Give then the price, if it is for your interest, for which it is sold. But if you wish both not to give the price and to obtain the things, you are insatiable and silly. Have you nothing then in place of the supper? You have indeed, you have the not flattering of him, whom you did not choose to flatter; you have the not enduring of the man when he enters the room.
