Minerva McGonagall was sitting at her desk, correcting the Trasfiguration essays for her 6th years students.

She looked at the clock on the wall: it was past midnight. Yawning, she decided to correct one more essay and then to go to bed.

She took randomly one essay and she read the name on the top: Harry Potter.

Well, let's see if he has studied... she thought with a tired smile to herself.

Then she realized that there was a very small sign under his name. Wondering what it was she wispered: engorgio. The sign grew bigger, until she could recognise two letters: GW.

GW? she thought What does it mean?

Then a sudden remember hit her.

She was in that very same room, sit on that very same chair, correcting some essay. She was looking at the clock: one more essay, she was thinking.

She had taken one essay and she had read the name on the top: James Potter.

Oh my God she had thought I hope this time he's not trying to convince me he really knows how people feel when they turn into Animagi.

She has seen a small sign under his name.

What is that? she had thought, while whispering engorgio.

And she had seen two letters: LE.

She had smiled: Lily Evans, again? she had thought That guy is madly in love with that girl.

She had chuckled, thinking: mmm, maybe they'll end up together. Imagine them... married... with a kid... she had laughed, trying to imagine a kid with Potter's untidy hair and Evan's big green eyes.

But no way this is going to happen she had thought she can't stand him.

GW, she read again. Of course! How couldn't she undestand before? Ginny Weasley!

She smiled to herself.

Sometimes story repeats itself, she thought.

And then she suddendly realized that it was the first time after sixteen years that she was thinking about James and Lily Potter without feeling the need of crying.

James and Lily. Finally she could think about them without sobbing or wiping her tears away, but just smiling.

She looked at those two letters again.

Harry Potter and Ginny Weasley. She had never thought about them as a couple.

But I never detect couples, she thought I could never guess that James and Lily could stay in the same room without trying to kill ech other. That Arthur and Molly Weasley were secretly kissing in the dungeons while almost pretending not to know each other's name in public. That Percy Weasley and Penelope Clerwater used to snog in the library until Madame Pince got them.

Harry Potter and Ginny Weasley, she thought again. And she imagined a young kid, with Ginny's read hair and with Harry's eyes. And this time didn't laugh at the image, like she had done in the past. Harry and Ginny's son she thought James and Lily's grandson, she thought again, still amazed that didn't feel the need of crying.

Life may seem unfair she thought but then gives back everything it took away.

She got up and went to her room, for the first time after the First War feeling happy. Life is good, she thought. Thanks God my students reminded me that.
