THE KIND OF REPETITION THAT RAPS IT IN
After you have observed Rule One: Get the Name Right, you must apply Rule Two: Rap the Name in by Repetition.
While you are talking to your new acquaintance, use his name as frequently as you can. Tack it on the end of sentences; begin your remarks to him by addressing him directly by name. Each time you speak his name aloud, you are driving it by one more hammer blow deeper into your memory. If it happens that other people are carrying on the conversation, and you cannot repeat the name aloud, then at least try saying it over and over again to yourself while you are studying your new acquaintance's features and general appearance.
