Your behavior in public.
Your behavior tells more about you, so whenever you are in the mist of people especially people you don't know, always mind the way you act and talk.
For example, am a type of person that don't talk or speak any how, and before i say any word i always think before i say it out. I think that's why am always accepted any where i go.
So your attitude and the way you talk tells more about you.
