The Prussian way of life is at an end. "Way of life". I'm not terribly fond of that phrase. It implies something about something. As if life is chosen or something. No, let's leave that where it is.
Why is it like it is? It's hard to say I guess. We wander in wonder. Asking too many questions leaves us in agony and crazyness. No, let's proceed, won't we?
You may wonder what this is. This is no why.
