Charles, I strongly suspect that what happened was that when she wasn't looking, Cari's boyfriend switched a blank disc for the one that she'd burned for you. It's likely that he's been telling her that you're probably some old pervert who's planning to eventually set up a meeting with her and do all sorts of lewd and indecent things. If she enthusiastically responded "Sounds like fun!", that might have irritated him even a bit more.
