Okay, she might drink vodka on the rocks if there's nothing else in the house--but she's of the opinion that most vodka drinkers, even or especially those who are so emphatic about only drinking Grey Goose, or Belvedere, or whatever, are fond of vodka primarily because it doesn't taste like alcohol once they mix it in with a bunch of sweet, fruity, girly shit.
