They don't even tell the truth to each other.. They are on stage here, 24/7, they are playing Kami and Kristy, not O. and S. And both are in the show business... Kami is also a bit of a drama queen, I like her a lot, but I understand she is playing her feelings, over and over. Sad in the morning, very happy in the evening, changing mood very quickly. Kristy is more stable, and sometimes tells Kami to stop her bullshit, in a nice way, always, at least in the apartment.
