From Business Cards to Business Relationships: Personal Branding and Profitable Networking Made Easy, 2nd Edition

Unfortunately, people will routinely give their first name only during introductions. Give your first and last name up front to make it easier for people to put you into context and introduce you to their contacts. Often it's the inclusion of the last name that will trigger an association that can lead to a conversation or discovery of a mutual friend.

When You Forget Someone's Name

When you're the person who has forgotten someone's name you may just need time for your memory to kick into gear, so continue the conversation and hope for a clue.

It's also acceptable to be honest, especially with someone you know you've only met once or twice. You could simply say “I'm trying to remember where we first met” or “Forgive me, my brain's obviously not working up to snuff. What is your name again?” Be sure to listen when the name is repeated so you remember it next time. Return the favor by offering your name, as well, to save others from having to ask.

If you've forgotten a name and you are required to introduce two people, simply ask, “Have you two met?” Naturally, the two will introduce themselves. That's when you listen to hear their names again.
