“知道自己在说什么”
用英语怎么说？

Rachel: Olivia. Monica: Olivia? I thought she was marrying Connor! Oh right, real life more important. Rachel: So do you think that my dream means anything? Monica: I don't know.

(Phoebe comes in Phoebe: Hey! Rachel and Monica: Hi.

瑞秋：奥利维亚。 莫妮卡：奥利维亚？我以为她要嫁给康纳呢！哦对，现实生活更重要。 瑞秋：那你觉得我的梦代表了什么吗？ 莫妮卡：我不知道。我的意思是，你看到他演了一场感情戏，所以也许你并不是喜欢乔伊，也许你喜欢的是德雷克。 瑞秋：啊！在梦里确实是乔伊在读德雷克的台词…… 莫妮卡：当然是这样了！相信我，当谈到心理学时，我非常知道自己在说什么。我在大学里上过两门心理学课。 瑞秋：你同一门课上了两次。 莫妮卡：那门课很难的！ （菲比走了进来） 菲比：嘿！ 瑞秋和莫妮卡：嗨。
