SAD
Sunday Afternoon Drinks.

Because regular folk have to work on Monday, it's wiser to start drinking on Sunday afternoon so you'll be wasted early and can go to bed in time.
Starting to drink too late on Sunday could seriously effect your appetite for

MND, TND, WND, ThND and/or FND and that would be sad...
A: Wanna meet for drinks on Sunday?

A: Noon then?

B: Noon it'll be.
