"In L.A., everybody ain't so nice"

This quote by Noah Hathaway recommends that the city of Los Angeles, or L.A., is not known for its friendly and kind occupants. Using the word "ain't" adds a sense of informality and colloquialism to the statement, implying that it is a frequently accepted fact amongst individuals of L.A. The word "everyone" also suggests that this is a generalization and not a particular observation. It could be analyzed as a cautioning to those who may be checking out or transferring to L.A., to be cautious and not anticipate everyone to be nice. In general, the quote paints an image of a city with a credibility for being less than welcoming.
