Calvin walked briskly to Geometry, smiling to himself. Oddly enough, his smile wasn't the direct result of the prospect of working with numbers and shapes for the next class period. Actually, his smile (which was really starting to look more and more like a dopey grin) hadn't been directly related to numbers for weeks. Not that he didn't still love numbers. It was just... Katie had more symmetry and elegance than the quadratic equation, and he loved her for it. Erm. Not that he could exactly tell her that just yet. Maybe one day...
