Andrew looked at her quizzickly.  Almost in disbelief.  "Fly?  You began to.....to fly?"  He repeated the words over and over in his mind.  Clearly she was delusional.  People can't fly.  It defies every law of physics under the sun.  This young lady was nice, kind, respectful, and clearly well spoken and urbane...but this was something he had a very hard time swallowing.  Flying...really.  He decided to humor her, trying very hard not to sound like he was doubting her.  "Ummm...you don't hear that every day...But...if you say you can fly...I believe you.  Is there any way, ummm...you can...you know...show me?"  If he saw proof, he would go from there...but proof was what he needed.
