Contact

A contact is a person that a Sim has at least interacted with once, (Including "greeting", "accepting deliveries", etc.), who has thus been added to your Sim's relationship panel. A contact can be reached by use of the telephone.

Contacts in Nightlife are Downtownies who have heard of your Sim from a mutual friend. They will phone asking to go downtown on an outing or date. The relationship between your Sim and the Downtownie is given a boost for a short period of time.
