When Antisthenes turned his cloak so that the tear in it came into view, “I see,” said he, “your vanity through your cloak.” To one who said, “Don't you find so-and-so very offensive?” his reply was, “No, for it takes two to make a quarrel.” We ought not to object, he used to say, to be subjects for the Comic poets, for if they satirize our faults they will do us good, and if not they do not touch us. When Xanthippe first scolded him and then drenched him with water, his rejoinder was, “Did I not say that Xanthippe's thunder would end in rain?” When Alcibiades declared that the scolding of Xanthippe was intolerable, “Nay, I have got used to it,” said he, “as to the continued rattle of a windlass. And you do not mind the cackle of geese.”
