People on social media are divided about something that, at first glance, doesn't sound that hard to figure out but is turning out to be surprisingly controversial.
A photo doing the rounds on Twitter has users trying to guess whether it is showing a beach or a door.
Now how could someone get those two things confused? See for yourself below.
The photo was posted earlier this week and has since gone viral and Twitter users can't agree on what it actually shows.
If you look at it vertically, it looks very much like it could just be a zoomed in photo of a door. However, flip it horizontally and you have the blue sky, perfect turquoise water and the golden sand of the beach you wish you were in right now.
The person who originally posted the photo conducted a poll online to see what people thought.
The poll received more than 211,000 votes.
A few hours later, she revealed the truth.
