Once I learned the rules of introduction it wasn't so bad. The whole who is introduced to whom, and how formal to be with names, etc, it's not bad. It's just sort of a social protocol that is pretty much required in polite society. Even if my kids have no interest in meeting someone I'm talking to in the livingroom, when they pass by I stop them and introduce them. It's just considered rude not to do so.
The easiest thing to do when you are introduced to someone by a third party is to just put your hand out and say "Nice to meet you" or if they say that first, you say "Likewise". After that you are pretty much free to walk off without seeming rude. When someone just comes up to you to introduce themselves you just put your hand out and say "Hi. Greer Bell, nice to meet you" and then you don't really have to say anything else. If they want to start a conversation with you then its up to them to do the talking and ask the questions. Unless you go up to them to introduce yourself, you aren't obligated to carry the conversation.
