Dumbledore, was often trivialised in Forums and fanfiction as being Dumb as a Door, for sending underprepared teenagers on a quest to destroy phylactery of the supposed greatest Dark wizard of all time. It even became a trope called Dumbledore bashing!
And he did very little, in his little time on earth, from the misleading pages of a book, I deeply adored, and the movies which I deeply abhored, due to their creative divergences from the characters as intended, into the characters as they appeared onscreen.
I had imagined quite a different kind of characters playing the role of Narcissa, Bellatrix, And Especially Tonks. And despite people loving her comic timing in Order of the Phoenix, I imagined a flamboyant and klutzy Pinkette who would greet people with a boisterous "Wotcher!"
And I absolutely hated the actors selected to play these roles. But back to my point.
Not only were the movies misleading, the books were too, and it made me want to give up on this charade, and offer the Horcruxes to Dumbledore saying, here you go! Take care of it, and make it all go away!
But I couldn't do that. And that meant, I had to appear bashful, as he praised me, because apparently, the Phoenix had put in a good word for me, since I informed Albus, that Fawkes absolutely hated Pumpkin seeds, and instead loved tropical fruit seeds. Quid pro quo, if you will.
So I casually brought up about his student Newt Scamander, and he agreed to introduce me to him, as well as his teacher and mentors, The Legendary Flamels, who would find it entertaining to have someone like me meet with them.
After that short respite, he decided to conduct his interview, while Aberforth asked me, if I saw any other creature which interested me. I decided to prank him, and brought a toxic snake back with me.
I hissed at the snake to not bite the man, and he can have a rat. The snake could smell the Basilisk on me, and obeyed me, and slithered towards a fearful Aberforth, who wanted to draw his wand.
He waited to see, with morbid curiosity, as the snake slithered up to his arms, and wrapped itself around him. The snake didn't hurt him, and he relaxed, but had his sight on the snake at all times.
After a while, when Albus came with my parents, they were greeted with the sight of my covered in snakes, and hissing at them and them hissing back in a rhythm, while Aberforth watched and smiled as he was entertained by me.
As one, all of us turned to look at three adults who just walked in, and the snakes continued hissing in rhythm, but I stood frozen in place. "This isn't what it looks like." I said like a child, who was caught not with his hand in the cookie jar, but with cookie jar between his teeth, and the cookies flushing down his gullet!
