Hermione hated when the library closed, especially now that she was here alone. Going back to the Weir, with it being quiet and empty, it wasn't the most pleasing thought. That's why she had decided to walk through the park on her way back, it would take longer and that would mean it would take her longer to get back to being on her own. She was in her own thoughts, clutching her books to her chest, not paying attention to her surroundings. After all, her feet knew where she was going, she'd walked this path a lot of times.
Pushing her hair behind her ear, she swore she heard something, but put it down to paranoia. Fighting in a war changed her that way. Even though they had one, she still was on guard for anything. Her wand was in her pocket, so she thought she'd have little trouble. So she kept on walking, not aware of the light footsteps that were behind her. After all, all she could hear was her own steps and the cars driving past in the distance.
