"I suppose so." Not that she'd have used those exact words, but it was still entertaining enough to agree to. "Practice. I know that's the simple way of saying it, but I've had a broom for a while, so it's...like your Muggle bikes? But it flies. I have not tried the bikes, though. Except when Sirius asked me to ride his motorbike once." And that had been traumatic enough. "You move the handle side to side." She demonstrated so he could see it in real time. It wasn't a harsh or fast turn unless you really needed to turn fast. Just a slow, careful turn at a much slower pace than she usually went, but this was for the purposes of teaching.
"If you want to go faster, get closer to the broom, like this." She started with a simple flying pattern before lowering her body toward the broom. She flew to the other side of the pitch and back, bringing her body back up and just slightly pulling up at the handle to slow down. "Then come back up and a slight pull at the handle to slow down. Not too hard again. Unless you like the ground." She smiled then to show she was lightly teasing. "Yours won't go that fast, but it's probably better that way." She was at least glad she'd plaited her hair instead of leaving it down today.
"And maybe one day you'll manage something like this." She rose up just a hair before flipping upside down and hovering for a moment before turning right side up again.
