    /* Explanation: I need to have a string that says "x days ago" BUT, if there's a word in the languague for it
    (like "yesterday" in english, or "gestern" and "vorgestern" in geman), use that instead. Obviously, it needs to
    support multiple languages, so no hardcoding of strings if possible.
    
    I've inherited a .stringsdict with "x days ago" in some languages (that's the @"RELATIVE_DAYS_NEGATIVE").
    I wanna avoid having external dependency just for that, but can be convinced otherwise.
    
    How horrible is this?
