Amazing optical illusion

It's a Disaster, at least to most of the male NYJCians... girls are treated to a free view of the boys in the Atrium toilet becoz the large mirrors are betraying their privacy!!! Oh No! O_O So the Student Council came to the rescue, installing foggy stickers on the mirrors, which of course, totally defeats the purpose of the mirrors, which then caused the uproar of many metrosexual males in the school. T_T So How? (getting desperate now...) >_< So somehow, someday, some ingenious guy suggested installing partitions around the urinals to block the view of proying "outsiders" which is of course, opaque (how convinient! It blocks LIGHT!!! The Perfect Solution!). And Somehow, in Someway, this idea got into the ears of the School Management, and action was taken... And so Finally... 0v0 It's There! The Perfect Solution. No longer shall wandering eyes set their sights upon vulnerable boys! No longer shall they urinate in uneasiness! And Whats more, they all have to walk the extra long route into the miserably tiny urinal space and cramp their poor selves against the damp place. How Thoughtful of the management! At Last! The Day Is Saved.... But Wait... Here comes the interesting Part... Hundreds of male NYJCians who used the toilet failed to notice a few things: - That Something is standing at the toilet entrance... - And that Something is gray in colour, which is totally Opaque... - AND That Something is able to close up the toilet entrance totally and block any prying eyes... AND......... THAT SOMETHING IS THE DAMN TOILET DOOR!!! Which is of course, supposed to serve it's purpose as the guardian of the toilet. Which of course is strangely, open at all times (The only toilet door that displays such behavior) Which is of course, beyond my all my comprehensive and understanding, FAILED to be noticed or acknowledged by NEARLY all NYJCians Now Thats What I Call Bizzare... Poor Door.....
