     Every day we meet people in a number of business and social situations. And the way we meet and greet

them creates an impression. It's important to do so in a proper way, no matter whether you are introducing

yourself to someone, or introducing two people to each other. To keep you aware of this, we have gathered

tips on how to make a proper introduction. 

     ★ Always stand when making an introduction.

     When you are seated and someone comes up to greet you, make the effort to stand up. By doing this, you

show respect for yourself and for the other person. 

     ★ Always maintain eye contact while making an introduction.

     Many people are not aware of the value of this simple action. When you make eye contact you are giving

a confident image. 

     ★ Always introduce a person of lesser authority to one of greater authority. The most important thing to

rememher is to say the most important person's name first. 

     ★ In a situation where rank is unimportant, _____. A man is presented to a woman and a younger woman

to an older woman.

     What if you find yourself in a situation where you have forgotten the other person's name? Start with a

handshake and reintroduce yourself. By doing this, you will usually cause the other person to do the same.

     However, if the other person does not take your suggestion, it is OK simply to apologize and let the person

know that you cannot remember her or his name. This is not the ideal situation, of course, but it does happen

to all of us. The other person should he forgiving.
