"Do you just carry on talking when I'm away?" A post-Reichenbach BBC Sherlock story. First person present tense.

“Love is a psychological and physiological phenomenon, made of synapses and hormones, endorphins and dopamine receptors, pheromones, experiences, commonalities, mutual attraction. Not the muscle of the heart. Inexact metaphor. Designed for poetry, not accuracy.” First person, present tense story told from Sherlock's point of view. Written in early 2011, prior to series 2.
