Harry paused, plate in hand. He hadn't meant to make them separate; he just hadn't wanted to watch. And he really thought they'd be better off without him right now, but now there wasn't really a choice, was there?

He put his plate back down on the table and sat down across from them.

Even though it appeared that Lily and Sirius had patched things up, he was worried that there'd be another awkward silence - things were already getting uncomfortable as it was - and so he took a bite of pizza and blurted out around it, "I couldn't get my hair to stop sticking up in the back. I put water on it, but it wouldn't go flat."

Which was probably the stupidest thing he ever said, but he truly couldn't think of what else to say.
