Seven years of being in the limelight had trained Harry how to speak to people without betraying his true self. He didn't lie exactly, but had instead developed a mask when dealing with the media's attentions. He found that it had been surprising simple for him to do. All he had to do was incline his head forward, drawing the reporters in, and overwhelm them with his smile. He could talk about how pleased he was to have the support of the Wizarding community and his hopes for a bright future, as through it was a secret that he'd share only with them, and their hundreds of readers.
Whenever the subject changed to the events in the Forbidden Forest leading up to the final battle at Hogwarts, Harry would sigh and look to the side, a pained expression across his face. Immediately, the interviewer would be able to sense his discomfort and edge closer to him, smelling a story. Harry would meet the interviewer's eye and say in a practiced voice of sincerity that his memory was still hazy and he couldn't remember much of what had happened. Disappointed at losing the big scoop, the interviewer would ask a few more questions about his plans for the future before thanking him for his time and that would be the end of the interview.
At times it could be hard for Harry to let go of the mask when he wasn't in public. Especially in the beginning. It had been easy for him to lose himself in the other Harry. The brave, confident Harry whose skill and luck had saved the World from a great evil.
But then Ron would hit him in the face with a pillow and say "Are you mental?" with a crooked grin. A pillow could break the mask, but it was Ron's crooked smile that would bring Harry back.
