Oliver smiled at him. "Thank you," he told Percy. It was good that Percy knew him so well. At least it was good most of the time. "You should just ask the twins, I'm sure they won't have a problem with it. I mean... is there a music teacher here? If not, then I bet it'd work out for you."
Oliver really wanted to hide his face. "No," he said, groaning softly. "I just... I don't know. I guess I'm just not feeling well." It wasn't even really a lie. He did feel sort of unwell, although it wasn't because of any actual physical discomfort or the like.
