Happy with a secret.

Stan: Hey. You got a lot of your stuff there, I see.
Mary: Yeah, that's right. My stuff.
Stan: I take it you're not coming back. I wouldn't come back if I was you either.
Mary: Do you swear you didn't know?
Stan: I-I swear.
Mary: So you didn't do the erasing?
Stan: Of course not. God, no.Mary: And you never even suspected we were together?
Stan: Once, maybe. I was coming back from a job, and you were at his car. I saw you two talking. So I waved to you, and you giggled, you know.
Mary: How'd I look?
Stan: You looked happy. Happy with a secret.
Mary: And after that?
Stan: I never saw you two together again like that, so I just-- I don't know. I just figured I was imagining things. I really like you, Mary Svevo. You know that?
Mary: Thanks.
