When you use this little tip, you also save people the embarrassment of forgetting each other’s names: Let's say you are introducing a Justin to an Ashley. First say, “Ashley, I’d like you to meet Justin. Justin this is Ashley.” Then, indicating each with your hand, REPEAT “Ashley—Justin. Justin—Ashley.”
Until you get used to it, you may feel awkward saying each name several times. But they will both be grateful for the memory aid—and everyone listening will be impressed with your sensitivity to the discomfort of forgetting someone's name.
