Richard searched his pocket for the keys for his classroom with his right hand, while holding a cup of coffee and a stack of papers in the other. After locating them, he used the keys and pushed the door open, flipping on the light switch with his elbow. He tossed his papers onto the desk and plopped down into his chair, looking ahead at the barren classroom ahead of him. It was still early in the morning, and school hadn't started yet. Richard took a sip of his coffee in an attempt to refresh himself, and started shuffling through his papers, preparing for the day ahead of him. Being a teacher could be stressful and tiring some days, though he was content with it most of the time and was thankful for the job.
