He stood there laughing, laughing loudly, laughing more than he had done in his life.
He did not find anything funny. Nothing to laugh.
But Harry was feeling such a relief, like a weight off your shoulders.
For the first time in his life, a real sense of peace had entered into it. He had to shout and celebrate, but could not do it. Then he laughed to take all your energy at once, he lightly wondered if would fall on the floor laughing.
He had done it.
After all these years with Voldemort trying to kill him at every turn, the wizarding world hoping he turned superhero and save everyone, a prophecy day and night pounding in his head.
Harry Potter killed Tom Riddle.
This feeling of freedom was asking to be used, then he laughed. A laugh of joy and relief.
Harry fell to his knees in the office of the director, his energies ending the raucous laughter, hands on his face. Slowly his laughter became increasingly lifeless, until it was a hollow, throaty sound.
So many people sacrificed for this war, and now he was alone again, like when he had entered this magical world.
Cedric, Dumbledore, Snape, Moody, Fred, Tonks, Remus, Sirius ...
He had friends, but nothing would replace those who were.
Leaning against the wall, laughing Harry was turning into sobs, tears ran on her face.
Insured tears from his first year at Hogwarts. He had cried on occasion, but not as much as he would have liked, did not have time for this, he had to save it to everyone.
So Harry cried, cried for all these years, cried for his parents, by his godfather, for all the people who had lost someone in this battle, mainly cried for himself.
To sleep, Harry sobbed and sobbed the rest of the night, praying that no one was aware that he left in the middle of the night. But now that he had finally begun to release all that was holding Harry could not stop.
They were tears of a lifetime.
