First line belongs to penknife.

In the beginning, Harry Potter was born.

James thinks that if someone ever has the unlikely urge to write down the story of his life, they should begin there.

As he holds his new son and gazes at his sleeping wife, he compares the life he has led to the life he will lead after this. Sirius had joked with him during his bachelor party about loosing Prongs to matrimony, about how everything was different now, about the end of their moonlight revels. James thought at the time that Sirius was, as usual, more right than even he knew. He can see the changes in all his friends, in Remus' increasingly lined face, in Sirius' bitter moods and longings he hides so well, in Peter's nervous twitching and refusal to sit still. He's not sure how to approach any of them anymore, is still unsure of how to talk to his old school mates now that school has come and gone and their actions have real consequences now. The real world has marked all of them, and James cannot say if it is for better or worse.

All of thses, however, seem insignifigant with the new life stirring in his hands and the young woman indulging in some well earned rest. He's been worried about his loved ones for a long time, but now, James Potter can see a better life ahead for himself. For all of them.
