Mike Pence is already melting our minds.

It’s only been a day since Donald Trump announced that the Indiana governor would be his running mate. But he already has us scratching our heads, after posting this optical illusion-style photograph to Twitter.

Busy weekend in NY! Enjoying a quick dinner with the family at @Chilis. Looking forward to getting back to Indiana. pic.twitter.com/SUFjYcvQpH — Mike Pence (@mike_pence) July 16, 2016

At first glance, it appears Pence is simply enjoying a meal with his wife, Karen, and one of their daughters. In fact, he captioned the image as such.

“Busy weekend in NY!” he wrote. “Enjoying a quick dinner with the family at @Chilis. Looking forward to getting back to Indiana.”

But on closer inspection, it appears that his daughter doesn’t have a reflection in the mirror that the trio is sitting beside. Take a look for yourself. Pence’s reflection? Check. His wife’s? Check. But his daughter’s? Hmmm, nope.

It’s sparked debate on Twitter, with some people questioning whether it had been Photoshopped or was the result of a bizarre optical effect.

Can someone please explain why Mike Pence's daughter does not have a reflection in that mirror? https://t.co/8GLIzMAc0T — James Skylar Gerrond (@JimmySky) July 17, 2016

But a contributor to the Stack Exchange online community explained that it all came down to “simple geometry.”

So now we know.
