Hahah, yeah, there'd be a timetable, and Sanji wouldn't understand why on certain nights, which always seemed to coincide with Nami being busy elsewhere, Zoro would insist on waiting before they got down to it. Zoro would stare into the darkness and Sanji would smoke irritably and wonder if Zoro was more touched in the head than he'd previously thought, and then Zoro would suddenly announce it was time to start. Sanji would try, on occasion, to see exactly what invisible force Zoro was staring at, only to have Zoro distract him in those most direct manner possible. Which would probably be for the best. ;)
