[Cueball and Ponytail are sitting at a table, eating from plates in front of them, Cueball using both hands with cutlery, Ponytail only holding cutlery in one hand, the other hand lying on her lap. Each has a wine glass standing on the table between the plates.]

Ponytail: Sometime around z=0.00000000038.
