Harry’s head was swimming. Hagrid, meanwhile, was counting bricks in the wall above the trash can. “Three up... two across...” he muttered. “Right, stand back, Harry.” He tapped the wall three times with the point of his umbrella. The brick he had touched quivered — it wriggled — in the middle, a small hole appeared — it grew wider and wider — a second later they were facing an archway large enough even for Hagrid, an archway onto a cobbled street that twisted and turned out of sight. “Welcome,” said Hagrid, “to Diagon Alley.”- Harry Potter and the Sorcerer's Stone, Chapter 5: Diagon Alley
I still feel very lucky that I am in a time where an entire world that I have known and loved for years is tangible. I can visit Grimmauld Place, Gringott's, Honeydukes, Weasleys' Wizard Wheezes, Sugarplum's, the Three Broomsticks, Hog's Head, the Leaky Cauldron, Madam Malkin's, Ollivander's, Gregorovitch's wand shop, the Owl Post, Quality Quidditch Supplies, take the Hogwarts Express and see and explore a bit of Hogwarts. I can be there.
There are so many other places and experiences that I am missing when I list the ones above, and I've done this before when it was just Hogsmeade. But I hadn't been back since. Coming home is such a wonderful feeling. I still have two more days to bounce between Diagon Alley and Hogsmeade and I feel so, so lucky to be here and see this. I feel so, so lucky to be with Tripp seeing this. I even crept into Knockturn Alley for a few darker kicks.
