If I haven't had anything to eat in town, I'll grab something from the fridge and probably have some water too. If I have any cigarettes left over, I might have one of those out on the balcony and then go to bed.
If I have friends staying over we usually sit and chat, while either having a smoke and/or something to eat. Y'know, to wind down before going to bed.
EDIT: But then there are also afterparties![]()
