When you're in the sort of mood where you think, "At least it's Friday," and then remember it's actually Wednesday... When you've analyzed more than a million rows of data that day and still left stuff simmering on the server when you left... When going in an hour early means you only leave an hour late...
You might need the drink I've tentatively named the Wednesday Night Special.
0.25oz Sweet Vermouth
4 dashes Orange Bitters
1 dash Angostura Bitters
Now why won't the kids put themselves to bed?
