It’s tearing families apart.

Are you a C2 or an F5?

If you don’t know what I’m talking about, you are clearly not hip to the very real and very important debate that is dividing the Internet.

It all started innocently enough: Delish posted a (bizarrely mesmerizing) coffee and cream matrix onto Instagram this week.

There were some C3s and D5s, and even a few F6s. I am saddened to report, though, that A1s exist—and they walk among us everyday.

Let me be clear: A1 is cream. There is not a drop of coffee to be found in that cup.

Understandably, people were unnerved by the revelation.

I’m not usually a judgy person—but if you consider yourself an A1 kinda person, you’re doing coffee wrong.
