Sonya Iosifovna Atlasova doesn’t hate a lot of people, but she utterly loaths her younger sister Katrina, since Katrina is a virulent feminist who has never forgiven Sonya for selling out, getting married and—horror of horrors—getting pregnant (with a son, no less!)
Katrina has been trying to lecture Sonya on how she’s ruined her life, but Sonya will have none of it, and is now trying to beat the stupid out of her sister. And if that doesn’t work, just beat her senseless.
