Zebra and Symbol have been together for a long time

Tom greeted Pete. "Hey, did you hear the news? Symbolina is marrying Zebra."

Pete looked puzzled. "I thought that Symbolina married Moto."

"Well, they broke up," answered Tom, "and now Symbolina and Zebra are getting together."

"I didn't even know that they knew each other."

"Of course they know each other. All those members of the Enterprise Club have known each other for years. In fact, a decade ago, Symbolina and Zebra were going out together, but they never got married because Moto swooped in."

"So all those Enterprise Club people are intimate with each other."

"Tell me about it."
