The document provides examples of how to reintroduce yourself to someone you have potentially met before. It includes questions to ask to determine if you have met, acknowledging a mistake if you were incorrect, and formally introducing people to each other. An example conversation is then provided where Sil meets Endang at an internet store and isn't sure if they've met. Sil asks Endang if they've met before at a party. Sil then introduces her friend Via to Endang and they have a brief conversation about their studies before leaving for class.
