Angel Hair
by Slantedlight
There are some names that Doyle doesn’t mind - Sherlock, Batman, even Raymundo - and some that are guaranteed to make his eyes flash. Goldilocks was pretty good, and the Bionic Golly, but Bodie’s latest soubriquet will do it every time.
Angel-hair.
“Get us another pint, Angel-hair,” he’ll say, reaching out to ruffle Doyle’s crop of curls, or “You finished that report yet, Angel-hair?” wrapping both hands around Doyle’s head in happy emphasis.
Yeah, it winds Doyle up something chronic, a good laugh.
It doesn’t have anything to do with being able to touch Doyle like that in public. Nothing at all.
