Most people who read this will think the same thing…who is she? I'm very well known, yet I'm not.

Well to start off with, most people call me Professor Sinistra, because I try to keep my first name a secret. Not even the great Albus Dumbeldore knows who I really am, although it still shocks me that he hasn't recognized my disguise. But perhaps he has, but has been considerate enough not to tell anyone.

The disguise that I let people see is this: A tall woman with thin brown hair that falls a little past her shoulders. Rosy cheeks and lips and many freckles beneath her eyes. A thin face and body, and a soft voice that unfortunately I could not change. But there's another part of me I could not change. My eyes.

If anyone recognizes me, it's because of my emerald green eyes. Which is why I grew my fake bangs out to cover them.

People don't realize how hard my life really is. They would get an even better idea if they knew who I really am, but to do that I could ruin everything.

My real name is Lily. Lily Potter for awhile, but after my husband died I went back to my maiden name, Sinistra. So as you can see, I am very well known as Lily, yet I'm not very well known as Professor Sinistra.

I'm not sure which sensation is stranger; dying or coming back to life, both of which I can honestly say I have experienced.

Oh, now I don't know where to start. Well I might as well start from Harry's third year. When my dear old friend Remus came to the school I couldn't help but let him know who I really was. He was ecstatic to see me, just as I was to see him. Near the end of Harry's third year, Remus told me that he had told Harry all about our time at Hogwarts…leaving out Sarah.

Sarah was the nicest girl I ever knew. She had brown hair, much like the one I use for my disguise. As a matter of fact, now I look just like her. After I died I became a ghost, but James didn't. Sarah researched day and night to find a spell that could bring me back to life. She finally found one, but it had the worst price of any spell ever.

First, Sarah would have to give up her own life, which she said she was willing to do. But the rest of price was just as horrible… I could never let the person I loved the most in the world know who I really was. I would be alive, but I could not let Harry know it was I.

Which is why my life is so hard. Not many people realize how hard it is to watch your son grow up without ever being able to tell him that you love him, or how proud you are of him. So many times I've been very close to telling him it is me…and every time I stop myself. I have to stop myself. If I let him know, we would both die.

Every time I see him crying for James and I, I want to hug him and cradle him in my arms like when he was a little baby, and tell him that everything is all right. But I can't.

Yet, I have a feeling that he knows I love him, and that I'm so, so proud of him. And I believe that deep down in his heart he knows it's me that sent Fawkes to him in the Chamber of Secrets, and that it was me that gave him more strength to fight the dementors.

I'm quitting my job at Hogwarts tomorrow. It's just too hard to see him grow up. So if anyone ever finds this, please, please tell my son that I'm very, very proud of him. And tell him that I love him more than I can put into words. My dear, little Harry.

A/N Hope you liked it. Sorry if it's too short, I wrote it to get over writer's block that I'm having for my story, Dangerous Secrets. Please, please review!
