Two words. One light. And nothing was ever left behind.
Harry knew this, he knew it better than most, but that didn't stop his fascination with the spell that had started it all. The spell that had given him more responsibility than anyone his age. It had marked him as a child, and followed him ever since.
Yet, it had never claimed him, never taken him without returning him to the living world, and that was worrying.
Because it had been years since he had seen anyone he had been to Hogwarts with, they had all either died in the war or lived long lives and died peacefully. It had been nearly twenty years since Ginny had died like that, surrounded by her family and friends, the ones who still remained, and him.
He didn't look like he was a year older than her, in fact, he looked around the same age as some of his grandchildren did, and he couldn't understand why.
There had been so many times he could have died, he would have died, and he had met yet another "Avada Kedavra" but had survived in one miraculous way or the other.
He could barely stand to meet his newest descendants anymore, and so he let them continue with their lives, knowing that they had some distant living relative yet never knowing they were directly related to him.
Harry was surprised the Department of Mysteries hadn't called him in for an "examination" yet. Surely it was strange for anyone to live this long?
It didn't matter. It would come as it came, like everything else did.
If there was anything Harry had learnt in all this time, it was patience, and so he would wait.
