Elbow
John
Pain.
John was used to it but he didn't expect to feel it on his sofa at home.
Looking down he saw the culprit and sighed, he should have known; Sherlock was all sharp corners and hard angles.
John shifted but only succeeded in getting his flatmate's elbow pressed more firmly into his ribs.

Sherlock
Bend and flex.
Bend and flex.
The elbow was a marvellous thing, an intricate contraption of bone, muscle and tendons that co-ordinated in perfect sync holding the arm absolutely steady in the heat of battle or bent at the exact angle needed to cradle a sleep-drooped head.
Perfect.
