Have you ever sat down and listened to the silence? It's never really silent, you know. There's a background sound everywhere you go. Now, that's just using your small human ears (assuming you're human, of course). What does the Doctor hear? What do I hear?

I'm so sorry; that sounded pretentious. I get like that sometimes. Martha tells me that's a habit of mine.

Do you know that your planet's rotation sounds like an air conditioner to me? I'd like to say it sounded like an ocean, or a nice sea breeze. But nope. Earth sounds like a noisy air conditioner.

Now, space is a pretty good place for me if I want quiet. No air particles for sound to travel. The drawback is when a meteor rushes toward me and I can't hear it. Nearly lost a whole incarnation there. Martha said I smelled of charred cloth for days.

Gallifrey had lots of silence.

Sorry. I'm getting mopy.

Susan was always really good with a flute. You should have heard her. I reminded me of the kloakalpy birds on Feriae, whose song could enchant someone for days. It's true that I had heard more sophisticated music from Gallifreyan Orchestras, but that didn't matter. She loved the flute. And whenever she played, it reminded me why I stayed on this planet with the irritating air conditioner sound.

Actually, the sound's not that bad nowadays. I think I've gotten used to it; maybe even fond of it.

Nah. I still hate that noise. It's the people on the planet I like. That's another thing about being silent—gives you a chance to think, and listen to footsteps. You humans pitter-patter so much! Do you kno one of the worst places to sit and think is in the middle of Manhattan? All those footsteps can almost drive someone mad! But I was always dragged there by Ro. . .

I miss Joan Redfern. She was a good woman. Actually, I miss a lot of people. Even Katarina.

Fitz would have—oh wait, you've never heard of him, right? Well, I never really mention him. Don't be surprised, there's a lot I never mention. Anyway, he was a rock musician who traveled with me in a former incarnation. Anyway, he would sometimes play music when we were just hanging out in the TARDIS. He would play 80s tunes that got the blood pumping. Back in those days, I was so innocent, and would just dance with Fitz and Sam (another companion I haven't told you about). Dancing and shaking till it felt like my hearts would fall out. Occasionally we would cuddle afterwards. I just saw it as being affectionate, but now I think that might have been a mistake. Humans take it deeper than I mean it sometimes. I hope not to make that mistake again.

Do you know that Martha' and I enrolled into a hugging competition the other day? Martha seemed so happy. But sometimes, I get the feeling something's bothering her. Don't know why.

Anyway, I think I'm done with my journal entry for now. Martha says that when you want to say something to a person no longer with you, putting it in writing helps. I do feel better, so I guess it worked.

So I guess what I'm saying is, when you're sitting there silently, remember to listen to the silence. Listen to the "music of the spheres." It gives you time to think.
