Lynne is on the phone. She tells the person on the other end that Dave has bought Deb a ring. The other person asks if it is an engagement ring and if the next stop is the church. Lynne says it is a rubber ring and the next stop is the beach.
Lynne is a horrible friend. She phones her friends, gets their hopes up with a bit of exciting gossip and then quashes it with, in her mind, a witty one liner. If she continues to do this either someone will mis-hear her punchline and spread untrue rumours or people will stop answering the phone to her. Either way Lynne is not going to be very popular.
