Adrian Monk: Oh, oh, the mail.
Natalie: Pardon me?
Adrian Monk: I forgot to tell Kevin to bring in the mail.
Natalie: That's okay, I talked to him.
Adrian Monk: Maybe we should call him, just to, just to be sure.
Natalie: Mr. Monk, I took care of it. He's bringing in the mail. [opens Natalie's backpack to take her cellphone] What are you doing? What, you don't believe me? Why would I lie about something like that?
Adrian Monk: To shut me up.
Natalie: Mr. Monk, I'm not a liar. I called him.
Adrian Monk: Just to be sure.
Natalie: Mr. Monk, we are partners now. That means we have to trust each other. That is the rule, okay? I have to trust you. You have to trust me. No matter what we say.
Adrian Monk: You're right. I'm sorry.
