     Being able to connect with others through small talk can lead to big things, according to Debra Fine, author of"the Fine Art of Small Talk."

     Fine and her fellow authorities on making small talk offer the following tips for starting-and

ending-conversations:

     1. As you prepare for a conference, come up with three things to talk about as well as four generic

questions that will get othe rs talking. If you've met the host before, __________, such as her passion for a

sport or a charity you're both involved in.

     2. Be the first to say"Hello." If you're not sure the othe r person will remember you, offer your name to ease

the pressure. For example:"Charles Bartlett? Lynn Schmidt-good to see you again." Smile first and always shake hands when you meet someone.

     3. Have something interesting to contribute. Keeping up with current events and culture will provide you with great conversation builders, leading with"What do you think of...?""Have you heard...?" Stay away from negative or controversial topics.

     4. Have a few exit lines ready so that you can both gracefully move on. For example,"I need to check in with a client over the re,""I skipped lunch today, so I need to visit the buffet," or you can offer to refresh the ir drink.

     When should you exit a conversation? According to Susan RoAne, author and speaker known as the

"Mingling Maven," your aim in all conversations should be to make a good impression and leave people wanting more. To do that, she advises:"Be bright. Be brief. Be gone."
