Milan Kundera said this quote
“ Back at home, after some prodding from Tereza, he admitted that he had been jealous watching her dance with a colleague of his. You mean you were really jealous? she asked him ten times or more, incredulously, as though someone had just informed her she had been awarded a Nobel Peace prize. Then she put her arm around his waist and began dancing across the room. The step she used was not the one she had shown off in the bar. It was more like a village polka, a wild romp that sent her legs flying in the air and her torso bounding all over the room, with Tomas in tow. Before long, unfortunately, she bagan to be jealous herself, and Tomas saw her jealously not as a Nobel Prize, but as a burden, a burden he would be saddled with until not long before his death. ”
