Theo flinched at Greg's use of words and the tone that was borne from exasperation but sounded too much like anger for Theo to be comfortable with them. As far as he was aware then he was in his head, the walls were his skull, this was all in his mind... he couldn't tell up from down and Greg was trying to make him see a snese that didn't exist to him.
He was too afraid to reply though and then Greg distracted Theo again with the book. He opened it and was so absorbed with its pages that he didn't even have time to shudder at the crisps Greg opened. "I can't read this." he said absently, flicking through it though, pouring through it, the words feeling like one of Greg's hugs, familiar and lost at the same time.
