Potter opened his mouth as though he was about to say something. Oh, no. He was going to correct me. Potter was going to tell Petunia that I had lied. He was going to say that he wasn't my boyfriend. I couldn't let him do that. For the love of Merlin, I could not let him do that. I had to stop him. He couldn't tell her the truth. So, I did the only conceivable thing I could think of to make him stop. I kissed him.
