When I first learned to fly it was more like floating. I showed my sister just little floats at first so she thought it must be some kind of David Blaine trick. I did that for a long time, so when I finally floated up to the ceiling and kicked off on the walls and swam around the room, she didn't lose her mind.

It is still really scary to go high or fast outdoors. I'm not invulnerable, and bumping into stuff -- or the ground -- hard -- can really hurt you bad. But I'm comfortable enough now flying home instead of taking the bus, for instance. If the weather's nice.

While I'm not invulnerable, I'm not invisible either, but that doesn't seem to matter. I can be at the park with my sister and fly straight up into the air and while she notices me, other people just tune me out. It's like when you see people who are hypnotized - they get a kind of blind spot and are unwilling to face it, and make up some kind of lie to themselves and don't think about it.

"Mister, did you see what my bother just did?"

"Oh, he left sweetie. He's not here now."

And they just go about their business. So I'm pretty safe flying around town whenever I want to. At least in terms of people seeing me.
