What's wrong with this picture? People question manners in viral photo

(WTXF/STORYFUL)- A tweet showing a blurred photo of a couple walking down a street has gone viral as social media users question one another, asking if they can spot what's wrong with the photo.

The photo which appears to have originated on Snapchat shows the couple waling side by side.

So what's wrong with the picture? Some spotted the issue right away.

In the photo the man is walking on the left side of the woman, while the street is on the right side of the woman.

According to popular etiquette, a man traditionally walks on the curb side, as a custom born from the idea that women needed to be shielded from potential hazards posed by passing vehicles.
