It's your ass that's getting bigger

Here, from every direction, I hear sounds of every kind: I live right above the public bath. Now imagine all sorts of sounds that can make us hate our ears: when the strongest men exercise and shake their hands while holding large red balls, or exert themselves or pretend to, I hear their sighs, when they exhale, and their hisses and unpleasant respiration. When some lazy person is happily being oiled in the most common way, I hear the sound of the hand that hits his shoulders, different when the hand is open or closed. Now, if a ball player comes and starts counting points, it's the end. Now add a troublemaker, and a thief caught in the act, and to that a person who enjoys hearing himself in the pool. Add those who jump in the pools, splashing. Besides these, whose voices are, at least, all the same tone, think about the depilator that speaks with a hollow and acute voice so that it can easily be heard and he is quiet only when he rips the hair from under the arms, forcing another to scream instead of himself. Think about the different screams of people who sell drinks, and those who sell sausages and pastries, and all the tavern owners who recommend their own products with a particular tone of voice.
