Maggie: "Can I ask you something?"
Barney: "Sure, go ahead."
Maggie: "Why are you so nervous around me?"
Barney: "I don't get nervous, Maggie."
Maggie: "Then what is it?"
Barney: "I just like keeping a distance."
Maggie: "Is it because you don't want to know anymore people?"
Barney: "Let's just say bad things have happened to people I've gotten close to."
Maggie: "Not a good way to live."
Barney: "I know."
