5am inspiration... Better late than never.
Dumbledore smiled as he watched 11 year old Harry Potter slip into the room once more. The predicability of the boy and the object in question of which Harry had come once again to see, was simply put down to childhood curiosity.
He watched as Harry walked up to the mirror and stared longinly into it. Dumbledore could only assume what was reflected back to the boy, but he had an instict that told him he was correct. Sweet as though it was to see the boy with a tragic story look into the mirror and see all he's eer wanted,
Dumbledore could not let Harry continue to return. Slipping silently out of the shadows, he walked up behind Harry and chuckled slightly.
"So-back again, Harry?"
Harry whipped around so quickly that his glasses slipped down his nose slightly. Stammering out an apology, Dumbledore raised his hand to silence him and gave him a warm smile.
"You have found yourself the Mirror of Erised. It shows you what your heart truly desires. Though it may seem harmless, the mirror is, in it's own way, a malevolent object. Men have crumbled before it, blinded by the desire that they may never truly have. It is a dangerous tool, Harry. I do not want to see you coming back here again. Do you understand?"
Harry nodded quickly, and was soon on his way back to his Tower. Dumbledore slowly walked up the mirror and watched as the cloudy surface swirled into an image so painfully sweet that it made Albus' heart ache with longing. There before him, was the image of two young boys slow dancing together; the head of a young boy with hair the colour of fire was resting on the chest of a boy with sunshine blonde locks who was holding his partner as though nothing else mattered to him. Golden bands on their ring fingers were enough to make Dumbledore look away. Bitter sweet memories of a time long ago came crashing back into his mind. It had been too long, yet his feelings never changed. The headmaster wiped away the few stray tears that began to escape from his piercing eyes, and turned his back on the mirror and the image that showed the two young boys who were happy and in love, and, as he always did,
he began to retreat back to his study to open the pensieve and watch the swirling memories of Gellert Grindelwald and himself inside a world that only they could penitrate.
