Black
I don't think I ever mentored that I nearly always drink my coffee, espresso, tea, or what have you without anything added, so I'm a genuine, bonified psycho.
Of course, I'm also drinking a cappuccino right now. Considering the hour, by Italian standards, I'm a raving lunatic and guilty of crimes against humanity (so I got that working for me, which is nice).
I rarely drink coffee, but when I do it's black. I prefer the world's second most popular beverage, tea.
I drink shots straight.
Everything else gets whole milk.
Um, wow!! You really like coffee!
Now I know who to ask for advice!
