When the man didn't seem to be angry or hostile in any other way, Nat relaxed a little. "Okay, so maybe I don't have a good explanation, but I mean no harm. I mean, I'm not intruding on purpose. I was going into the supply storage to restock the ambulance, but found this and I'm too curious for my own good. I'm so sorry if I'm disturbing you, sir. And magic? I don't know what you're talking about, I know no magic. There's nothing special with me. I'm just a perfectly average human guy, yes. Letter? Do people write those still? I only get junk mail and bills, but this place seem like a letter kind of place." There was a pause, even he needed to breath sometimes, having a tendency to ramble quickly when nervous. He was also a worthless liar and it was obvious that there was something with him that wasn't average human guy, but he would never just tell anyone he actually could heal people. Few would believe him anyway. "I'm rambling, sorry." He then added, giving the older man a sheepish smile.
