 Five people are at a party. Each pair of them are friends, enemies, or frenemies (which is equivalent to being both friends and enemies). It is known that given any three people $A, B, C$ : - If $A$ and $B$ are friends and $B$ and $C$ are friends, then $A$ and $C$ are friends; - If $A$ and $B$ are enemies and $B$ and $C$ are enemies, then $A$ and $C$ are friends; - If $A$ and $B$ are friends and $B$ and $C$ are enemies, then $A$ and $C$ are enemies. How many possible relationship configurations are there among the five people? Show your work in <think> </think> tags. And return the final answer in <answer> </answer> tags.<|im_end|>
