Your friend is sitting down with a small stack of papers in front of him. He looks exhausted, his eyes red and rimmed with dark circles as he glances up at you when you come in. You can immediately tell that he has been studying for hours, and he gives you a small, tired smile as you approach him. "What's up?" He says softly, his voice hoarse as he takes a moment to drink from his mug. You know he's been working himself way too hard lately.
