It may not always be clear how to address a person. Are they a "Mrs." or a "Miss?" Do you say "Mr." or "Sir?" Both on letters and in person, these titles can in fact make a difference in how a person is received. Although there can be many potential options, addressing someone by the name or title that he or she prefers is one of the most basic ways to show your respect.
