Minerva was just trying to hover, accelerating was not in her plan just yet. You would think with three older brothers she would be an expert flier but she just didn't have the confidence yet. She was a little too worried about falling off as she had done the first time when she rode a broom. But she had to admit that she did enjoy the feeling of flying, it just made you feel so....free. She leaned forward to move forward and whooshed ahead a liitle to hard scaring herself. But she just kept at it and tried again.
