Roommates have a falling out

[Charlene]

The lighter haired woman is trying to concentrate on a financial task, while the darker haired roommate is enjoying a cup of coffee and listening to music.  The problem arises when the lighter haired woman is having trouble concentrating, and asks the darker haired woman to put on a headset.  She refuses, and it escalates until they end up facing each other, cursing and screaming.

The darker haired woman appears to be the overwhelming favorite so far ....  I wonder why?
