And it was pointless...to think how those years could have been put to better use, for he could hardly have put them to worse. There was no recovering them now. You could grieve endlessly for the loss of time and for the damage done therein. For the dead, and for your own lost self. But what the wisdom of the ages says is that we do well not to grieve on and on. And those old ones knew a thing or two and had some truth to tell...for you can grieve your heart out and in the end you are still where you were. All your grief hasn't changed a thing. What you have lost will not be returned to you. It will always be lost. You're left with only your scars to mark the void. All you can choose to do is to go on or not. But if you go on, it's knowing you carry your scars with you.
