On Monday, Isabella Koval tweeted out two screenshots of the same photo.
Here's a better look at both captions:
From the moment she tweeted the two screenshots Isabella's tweet started moving. Two days on, almost 40,000 people have retweeted her.
And she has accidentally encouraged a bunch of other couples to share their Instagram captions. Turns out Isabella and her boyfriend aren't the only ones who approach captions from different planets.
"Sean choked on a piece of cheese stuffed crust the other day and almost died, I'm glad he didn't" versus "Mary eats ass."
"Because of you, I smile a little bigger and laugh a little longer" versus "Wizard kelly with the Sky Hook".
"My favorite person" vs. "Ravioli ravioli give me the formuoli."
"Thanks for being the best date I could've asked for" versus "Meat sticks or nah?"
And "I like green and dis boi" versus "Some green shit".
Isabella's boyfriend didn't even know she was posting their different captions on Twitter. "It was really unexpected; when he saw our posts side by side he thought it was hilarious, but really didn't think anything of it until I pointed it out," she said.
"Seeing all the other couples tagging each other was a trip."
