三个孩子，她是老二。

She's the middle child of three.

“老二”通常会成功地与其他“老二”结婚，因为他们都很乖巧，不那么强势，并且渴望感情。

"Middles" often successfully marry other "middles", since both are strong on tact, not so strong on aggressiveness, and tend to crave affection.

“我不明白它怎么能有一个快乐的结局。”双胞胎中的老二说。

"I don't see how it can have a happy ending," said the second twin.
