The sun was high in the sky and Sirius could not join his friends for a Quidditch match, nor could Dawn study in the school library (Sirius would never allow it). And so they sat under a tree, sighing, every now and then as they reluctantly turned away from everything they would normally do alone.

-I'm so bored."
-Shut up, Sirius."

Dawn thought about how she was going to go through life possibly dragging along such a macabre person as Sirius…

-You know, we're almost like- oh, what're those called… Siamese twins."
-Shut up, Sirius."

And how she was going to kill him if he ever came up with a smart-ass remark like that one again…

-I'm wondering, Dawn, what're we going to do about tonight?"
-Shut up, Sirius."

And if she was really going to have to sleep with him…

-Oy, Dawn, what's your favorite color?"
-Shut up, Sirius!"
-Just trying to make conversation."
-Yeah, all right. I'm bored too. No, I don't think we're like Siamese twins, because if we were, we'd be sharing at least one limb. I don't know how tonight's going to go, and I'm not looking forward to it. And I don't have a favorite color."
-Wow."

Sirius thought Dawn was unnecessarily angry. Sure, they'd be stuck together for a while, but there were some benefits, like copying from her during class, and peeking into the girl's bathroom, for instance.

-How come you don't have a favorite color?"
-I've never thought about it." Dawn growled, annoyed. "Would you just be quiet?"
-Grr.

Sirius thought that Dawn was very weird for not having a favorite color. He was sure that was a subject girls liked to discuss. He also thought Dawn was not much fun to hang around with.

-Dawn, I'm bored."
-Me too."
-Me too."
-…" Dawn squinted at Sirius, who smiled back innocently. "Are you… copying me?"
-Are you… copying me?"
-Sirius, that's stupid, stop it."
-Sirius, that's stupid, stop it."

'Sounds like a tongue twister.' Sirius thought, amused, 'Sirius that's stupid stop it Sirius that's stupid stop it Sirius that's stupid stop it Sirius that's stupid stop it.'

Dawn sighed. Sirius sighed. Dawn hit Sirius. Sirius hit Dawn. Dawn got up and left. Sirius was pulled along. Dawn yelled. Sirius was scared.

-I'm going insane!" She said. "If I have to stand you any longer, I honestly think I'm going to lose it."
-Sorry I'm so normal."
-That's the thing, Sirius, you're not."
-Oh."
