The Wizarding World of Harry Potter is vast and magical, complicated and complex, ingenious and spellbinding. There are magical places for wizarding needs, several places for magical education, depending on where one lives, laws, magical foods, magical sports and games, and a ministry for magic.
It is a whole different world, a fantasy, yet it became so real to so many. Some things are brilliant and breathtaking, some are illogical, and others are mysteries to both muggles and wizards. Fans take to creative means to make observations and address content from the books and films.
Hogwarts' Security
The.maraudersmemes has highlighted the fact that Hogwarts is a constant place of infiltration - a place that has about as much security as a cheese puff has structural integrity in place of a lock.
Voldemort and Quirrell were hired, Tom Riddle's diary came in with the luggage, Sirius Black broke into the grounds, Barty Crouch Junior made an appearance in the form of Mad-Eye Moody, there was murder on the grounds, cursed items thrown into the mix, and a break in via Vanishing Cabinet.
The Hogwarts Sorting
No one is one quality. "We've all got both light and dark inside us. What matters is the part we choose to act on. That's who we really are."
No Hogwarts House is simply one thing or another, accepting only a certain type of personality. Although it might appear that way at first, as shown by Carl Kinsella's post of the Hogwarts Founders, in reality, each House is far deeper and more complex than the Sorting Hat's song suggests, especially if one looks at the lyrics with a fresh and reasonable perspective.
The Ministry Of Magic's Denial
It didn't matter what Harry said, the Ministry of Magic corrupted his words and made him look like a fool. They blamed Sirius Black for the signs of Voldemort's return, ignoring any claims or proof presented by Dumbledore and other esteemed voices of reason. Fudge called Cedric's death an "unfortunate accident."

Owls
Prongsmydeer brings up a valid point in this text post. How do owls really work in the Wizarding World? Are they magical? Have they been trained?
At one time, Harry had written Snuffles on the envelope he was sending to Sirius as code for if the letter was intercepted, but told Hedwig that it was really for Sirius. Pottermore explains that the process is a mystery, even to those who train owls to become pets or postal owls.
Harry's Wizarding World Welcome
For 11 years, young Harry Potter had no idea the Wizarding World even existed. He had experienced things he couldn't explain and was punished by the Durselys, who knew what he truly was.
The night Harry was placed on the Dursley's doorstep, wizards flooded the streets and celebrated Voldemort's apparent defeat. When Harry was told that he was a wizard and entered the Wizarding World, he had no idea what he was in for. The Office.
Quills & Inkwells
Writing with a quill and ink is an art. Without the correct form, there are sure to be inkblots, smudges, and illegible writing. It's especially difficult if one is a muggle who is making the change from pen and pencil to quill.
But ink and quill does have quite the aesthetic and a magical feel to it. When someone thinks about Wizards, modern things don't really come to mind. But logically, as danielkanhai points out, it doesn't make much sense. Maybe there is a solution in the fountain pen.
All Exams Are Cancelled
Dumbledore is the Heaster of Hogwarts. Does that give him the authority to cancel school exams? Yes. Does it give him the authority to cancel O.W.Ls and N.E.W.Ts? Probably not. The future of those students is safe, or relatively safe, depending on how well they do in their exams and their dependence on the results, or if they even need them for their chosen career path.
So even if Dumbledore did cancel all exams, the students could choose to complete them. The O.W.Ls and N.E.W.Ts are only hosted by Hogwarts, while their content is created by the Ministry and overseen by external examiners. As harrypottermemes has shown, the initial announcement would still manage to create some panic.
The Goblet Has Spoken
The Wizarding World is pretty intense, especially for Harry. He faced obstacle after obstacle from the moment he was told he was a wizard. He was the Chosen One, and with the title came his destiny.
One challenge began after his name came out of the Goblet of Fire when he hadn't put it in, to begin with, In fact, he was underage. Charlesoberonn shows the Wizarding World's decision in comparison to what the muggle world would have done.
Fake News
Rita Skeeter was the gossip provider in the Wizarding World and everyone just drank it up. In the novel, she is revealed to be an uned Animagus - a beetle. It was how she knew so much about private matters and was able to listen in on conversations. She exaggerated, twisted, and wrote unsavory articles about whoever and whatever she could. But the Wizarding World still read her words with great enthusiasm, as harrypottermemes clearly shows in this meme.
A Different Plan
There are many ways Harry could have been moved from Privet Drive to a safe and protected location. The plan they chose, however, was one of daring and danger. But hey, they were moving the Chosen One, so any plan would have included some form of danger.
