It's rude to make assumptions based on skin color.
Kristen's brother recently started dating an Asian girl named Kelly.
Kristen wants to get to know Kelly.
Kristen asks Kelly where she works and what her hobbies are.
Kristen asks Kelly if she works for a nail salon since she is Asian.
Kristen and Kelly get to know each other and become friends.
Kelly is offended by Kristen's question and walks away.
