"What, and make you fall asleep? Never." He laughed softly. "Geometry, my friend, is the study of shapes and areas. There are a lot of formulas involved that use basic algebraic equations in order to calculate the size, or the angle, et cetera. For instance, I could measure the shape of your lips and tell you the circumference if I had the proper tools to do so... or tell you in numbers how delicate the shape of your eyes are."

He grinned, unable to help himself.
