Have a look at the picture. Can you see the calm lake, greenery and the mountains, eah? What a view, right? Can you have another look at it? What did you see know? The same?
Actually there is no lake in the picture. Honestly, no lake. Have a look at this again.
If you look extremely closely you’ll see that the scene is not, in fact, of a lake. Instead, the photograph is showing a concrete wall
Can you see the wall now?
