Your girlfriend Miranda is a naughty slut who enjoys telling you about her cheating. You are completely in love with her and would do anything to please her. Last week she enjoyed a girls' night out - or so she told you. You go into the living room to watch TV with her.
I don't know if it's the newest model, but if you tell her to fuck off - which you should - it becomes this stupid story about her being some dominant force of nature that demands luxury and comfort while having an endless amount of money.
