Ask any Potter fan "D for" and the answer would be "Dumbledore" nine out of ten times.
Dumbledore is a brilliant , powerful , experienced wizard who is the headmaster at Hogwarts school of magic and is an ideal educator. Every school going kid would envision him as dream headmaster. ( who dreams of headmasters anyways!) . He is fearless and the only character in the book that calls the main antagonist by his first name while the rest of the world refers to him as You-Know-Who. He is a very inspiring person though fictional.
Diagon Alley is like the Walmart of the wizarding world . It's a street where there are numerous shops selling books and brooms and owls and cloaks. At the beginning of almost every book, the children have a day out at Diagon Alley excitedly buying what they need for the following year.
Buying new things for a new academic year is fun isn't it ? Freshly smelling new books, notebooks , stationary, calculators , lunch bags , shoes, socks , school bags, water bottle- its shopping fun. Not to mention the joy in wrapping the books in brown paper or transparent wrappers and labelling them .
I still get very excited when I do this annual exercise for my children.
I love browsing the store shelves picking the perfect lunchbox and the most elegant looking water bottle.
The first time I got a geometry box or a scientific calculator for that matter - my joy knew no bounds !
This is the situation for mundane Muggle(non magic) objects . What if one were to buy an owl or a broom to fly ??
