I Know

Vanessa Hill was a woman of habits. She knew when she was supposed to be awake. What time she could leave if she rode her bike to the train station. What colors looked best on her in all seasons. There was little room for variance or error. It’s not that she was picky, she thought as she pinned her hair up in the tight bun that kept her looking professional and proper.
Things just had an optimized way to be done and Vanessa worked tirelessly to find them. Every day scheduled, every moment planned. Her friends would joke that she could take her routes to work blindfolded because she had counted how many steps from her stop to the building her office was in. Vanessa Hill liked order.
