John gaped at him for a moment. But than he grinned widely. "How'd you so that? That was amazing!" He said. "Can all people here do that?" He asked. He hoped not - otherwise it would seem kind of stupid for him to get so excited over it. He was still kind of mystified how the boy had know that about him. Maybe he could teach him that trick? Did have something to do with magic? He hadn't seen a wand or anything. His blue eyes were still wide, and he wasn't embarrassed to say he was quite impressed. He was beginning to wonder if he could ask for him to do it again, on someone else. He kept his mouth shut though, just waiting patiently for a reaction at his outburst - hopefully it wouldn't be negative, or one of contempt or irritation. He was almost sure the boy heard it all the time.
