Fighting and conflict and 
dissidence and animosity...
Streitereien und Kämpfe,
Las peleas, conflictos,
disidencia y animosidad,
La animosidad, las peleas, 
los conflictos y las disidencias
Je n’aime pas du tout les disputes,
conflits, dissensions et discordes.
Litigi, contrasti, disaccordi e risentimenti...
Lutas, conflitos, 
 divergências e animosidades...
