We join Harry as he is attempting to write an invite to Luna for Slughorn's Christmas party.
Dear Luna
I have been invited to Slughorn's Christmas party, and I thought that maybe you would like to join me.
No that isn't quite right
Dear Luna
It is getting close to the wonderful time at Hogwarts known as Christmas. Everything is always so beautiful out here during this time. It reminds me of my first Christmas at Hogwarts, and how for the first time ever, I had a real Christmas. Now I would like to be able to make a memory better than that with you.
Wow, I'm kinda pathetic at this...
Dear Luna
I am the chosen one. Would you like to join me for a party at Slughorn's?
Nah, to arrogant
Dearest Luna
Last year was the first time we met. The first time you spoke to me it was to say "you're not crazy, I can see them too." I didn't know you very well then, but throughout that year I got to know you very well. You were one of the few people to speak out and get me to help teach the DA. I remember how fun your Patronus Rabbit was when trying to teach everyone. You were incredible at learning the spells, and your enthusiasm often was all I needed to keep going. Then you even helped to defend me when I needed it most. You helped to watch my back at the Department of Mysteries. Then at the beginning of the next semester you were able to find me hidden underneath my invisibility cloak, so I didn't end up not getting to the castle in time. You even mended my nose when I really needed it. There are times when I just dream of getting to see your face amongst your beautiful hair. Now that I have thoroughly gotten off track, I was wondering if you would like to join me at Slughorn's Christmas party next week. I would be honored if you did.
Sincerely
Harry
Now, how do I get this to her...
