Sienna threw open her apartment window. The heat wave was almost unbearable, and her wavy bob of black hair clung to her neck with sweat. Irritably, she stalked into the kitchen, grabbed a coke bottle, and climbed out the window to sit on the fire escape. She took a swing, and watched the traffic go by four stories below. Sienna smiled to herself as she raised her gaze upwards to the skyline. Downtown was famous statewide for its food, and her apartment was only a few blocks from her favorite restaurant. Sure it was a little rough around the edges, but what city wasn’t? Below her, people walked between the shops, sitting on porches, and calling out to one another as they passed. She sighed. It was so peaceful here, and though this week was ungodly hot, there was still room for enjoyment. Tonight seemed like a good night to go out, and the way work had dragged on, and Friday nights always made the city seem more lively.
