Yukarin is seventeen. ♥ In other words, I think I simply stopped caring to remember.

Really, age is just a representation of history. It does not bring with it wisdom, maturity, or knowledge like many believe; these things take time to achieve, certainly, but they are not instantly gained at some arbitrary milestone.

So does that mean that, if you are immortal and do nothing for an entire year, you have wasted it? Hardly - to experience is to create history, after all.

[She's had more than one discussion with the children of Miare about this, even if she wasn't exactly the best company.]

It depends on the strength of the memory. Incredibly momentous occasions remain far longer than simple day-to-day life. It's a lot easier to forget the death of a celebrity or random acquaintance than it is to forget the death of a loved one, as an example.

As I said, though, the typical threshold is sixty to eighty years. Both for me, and the world. Just think, in a few more years, everybody who remembered the Great War in the outside world will have passed, and it too will fade into the background.

I don't even remember my parents, if I had any.

I told you. Seventeen.

Which is somewhere around six times your age, I would wager, though I have absolutely no proof past a hunch.

I suppose it also depends on perspective. The one called Yukari Yakumo had no parents but herself.

Well. It could be said that I'm my own parent, so I don't truly have none.

It's not uncommon for those of longer lives to have forgotten who birthed them, though, if they outlive their predecessors by a margin of centuries.

Long enough for dynasties to rise and fall alike.

So is a special milestone drawing near? It's unlike the human mind to think of such thoughts without provocation.
