When she’s having sex with her boss, Iris likes to have the lights on so he can see how much younger she is than his wife.

She likes watching her colleagues eat unhealthy lunches at their desk while her stomach aches with emptiness. She likes coasting at work knowing she’s going to land a big promotion anyway.
