Category talk:Fiction about family

??
What exactly is this category for? The articles categorized in it seem rather random and (I assume) all have family as a somewhat important thematic, but how is it decided what things have enough focus on family? Don't most character-driven stories have a somewhat important focus on family, family relations and kinship? At least "Works about families" is clearly about works that have a major focus on family, but that one too seems very vague. How do we define articles as falling under "family in fiction"? ~ Mable ( chat ) 19:56, 2 June 2015 (UTC)
