Almost every afternoon, the Woman in the Purple Skirt sits on the same park bench. Unbeknownst to her, she is being watched --- by the Woman in the Yellow Cardigan, who is always perched just out of sight. From a distance, the Woman in the Purple Skirt looks like a schoolgirl, but there are age spots on her face. She is single, lives in a small apartment and is short on money --- just like the Woman in the Yellow Cardigan, who lures her to a job as a housekeeper at a hotel, where she too is a housekeeper. Soon, the Woman in the Purple Skirt is having an affair with the boss, and all eyes are on her. But no one knows or cares about the Woman in the Yellow Cardigan. That's the difference between her and the Woman in the Purple Skirt.
