We have talked about how you introduce yourself.  Make sure you have a good attitude and follow these steps:

1) Face the person
2) Eye contact
3) Smile
4) Greeting
5) Handshake or nod
6) Lean

But there will be times when you will be making the introductions for people that you know.  There are a few protocols to follow when making these introductions.

• Introduce the younger person to the older one.  For example, if you are introducing your friend, Bob, to your Great Aunt Gertie, you would say, “Great Aunt Gertie, I would like you to meet my friend Bob.”
• Introduce a man to a woman.  This one may sound a little old-fashioned, but you never know who has old-fashioned notions and who doesn’t.  Better safe than inappropriate.  For this one, you would introduce your friend, Bob, to your cousin Jane (e.g. “Jane, this is my friend Bob.  Jane is my cousin.”).
• If you are in a business situation, hierarchy takes precedence over age or gender.  For example, if the president of the company (the young Mr. Patterson) and a new employee (the older Mrs. Whig) are being introduced, the person making the introduction would introduce the new employee to the president by saying, “Mr. Patterson, I would like to introduce you to Mrs. Whig, our newest addition to the accounting department.”
• Use courtesy titles during more formal introductions

Mr. – an abbreviation for Mister – used for a man, married or unmarried
Mrs. – an abbreviation for Mistress, but pronounced “Misses” – used for a married woman
Miss – used for an unmarried woman or young lady
Ms. – pronounced “Miz” – used by women who choose not to make a statement regarding whether they are married or not
Master – used for boys, though not widely used now.

• If the person is a doctor, minister, rabbi, or has another specific title, use his or her title during introductions.

Err on the side of formality. 

Here in the South, children often use first names preceded by the titles “Miss” or “Mr.” when addressing adults (e.g. Mr. Tim or Miss Kim).  In other parts of the country, that would be considered poor taste and adults are addressed by their titles and last names (e.g. Mr. Smith or Mrs. Jones).  If in doubt, use titles and last names (e.g. Mr. Smith or Mrs. Jones).  If the person would rather you call them something else, he or she will let you know.
