always tag you two ok

when sherlock starts to really go grey john can tell it bothers him even if he just huffs and dismisses john pointing out his pepper hair and later that night when john sees sherlock frowning at his reflection john comes up from behind and runs his fingers through his hair and kisses his neck and calls him dashing and anytime it happens from then on out that’s what john does (and john knows sometimes sherlock does it on purpose just to goad him into affection but he doesn’t mind giving it at all especially if it makes sherlock smile)
