Heartless

A prostitute stood by the door, and when she saw a guest passing by, she pulled him in and got to work. Upstairs, at the doorway of the opposite building, two women, a sister-in-law and her younger sister-in-law, pushed open the window and saw what was happening. The elder asked the younger, 'Why is she pulling him?' The younger replied, 'She wants to sleep with him.' Soon the matter was finished, and the prostitute took a small scale and a pair of scissors to hand over to him. The elder asked, 'What does she want to do?' The younger replied, 'After sleeping with him, she wants him to pay money.' The elder sighed and said, 'How heartless, to still ask for payment afterwards.'
