A great difference between American social customs and those of other countries is the way in which names are used. Americans have little concern for "rank", especially socially.

Many Americans even find the terms "Mr. ", "Mrs." or "Miss." too formal. People of all ages may prefer to be called by their first names. "Don't call me Mrs. Smith, just call me Sally." Using only first names usually indicates friendliness and acceptance. However, if you do not feel comfortable using only first names, it is quite acceptable to be more formal. Just smile and say that after a while you will use first names but you are accustomed to being more formal when you first meet someone.
