"Home sweet home!" Mr. Evans exclaimed, closing the door to his apartment. The air was warm and inviting after a long day at school. He practically skipped into the kitchen, the weariness of the week melting away. He’d had a particularly wonderful conversation with a student about the beauty of mathematics.

A delivery man handed him a large, sturdy package. He signed the receipt, feeling a curiosity he could barely contain. Inside, he found a brand new, top-of-the-line set of drafting tools, complete with every imaginable gadget and gizmo. A card read: "To the best geometry teacher ever. - Michael." He grinned, feeling a swell of affection for his former pupil.
