Even so, she didn't miss the black haired man who seemed to perk up at the sight of her and stepped forward to offer her a hug. Ginny figured he was probably a quidditch fan, or possibly just a random stranger who tried to feel up unsuspecting women. Either way, she side stepped him easily enough continuing on her way down the block while flexing her arm to make sure that her wand was still nestled in the holder she had wrapped around her wrist so that she could draw it easily if she needed too.
