As a person
If you want to meet someone at a party or at a reception, you better find a mediator who is familiar with both of you, to have it presented. If such a person can not find work, then yourself. If someone starts to introduce myself to you, name in response to his name.
Remember that during a handshake the hand first takes the one who submitted. Remember that hand feeding is necessary at the last moment, so as to go cap in hand rude and ugly.
If you are someone, in response, say "Very nice" or "nice to meet you". The person you are not obliged to answer you.
Remember that young people should be presented first, and then older. First man should greet woman, men, Junior in rank and position, must first greet the elders.
Remember that if a woman enters the room, where already gathered a company, it should be presented first, and the men in this case have to wait for the woman to come over and greet them. And if the first woman leaves the company, she must say goodbye first.
While meeting and greeting always be friendly, if you want to observe the rules of decency.
The more you pleasant acquaintances and meetings, and be polite!
