What is the proper way to address someone who I've just met?

The most important thing when addressing someone you have just met is to make sure that you are respectful. Use their name and be polite, but avoid using overly familiar terms like “honey” or “sweetheart”. You can also use a title such as Mr., Mrs., Miss, Dr., etc. depending on how well you know them. If it's appropriate, you could also ask for their first name.
