Amy and Klara have similar interests. They both read Cosmopolitan and Salon.com, for example. But they do not get along. Not at all. Maybe Klara’s thick German accent bothers Amy. And neither of them particularly likes the color pink. Unfortunately for Amy and Klara, they live on the same block and have pink houses! And when they become agitated they tend to fall into mutual accusations and even rants. Yes, it can get rather nasty at times. Best then just to leave them be and to stay clear of the hissy fits. Else you risk being drawn into the fighting.
