Advent Drabble 15 - Family

For kylaraingress 

“Family” is a word that Sherlock finds it difficult to define. It’s easy for him to accept that Mycroft is (lamentably) their family, but Oliver expands the definition to Lestrade easily, uncritically. At the foolish school he attends, he brings home drawings of his “family” – the school is obsessed with talking about “family” – and the drawings always include Mrs. Hudson, even though Sherlock has told him a million times that they are not related to Mrs. Hudson.

Oliver tells him scathingly, “I don’t think you understand the definition of ‘family,’” and Sherlock thinks maybe Oliver is the one who’s right.
