What can playing the piano teach us about building a happy marriage?

Not much, but perhaps this conversation that took place moments ago between my wife and me can lend some insight.

Sassan: [playing piano, keep hitting wrong notes, giving up in frustration] Gah!! I hate B-flat major!
Janet: Pardon?
Sassan: I hate B-flat major.
Janet: Okay.
Sassan: You see, Janet, that's something you didn't know about me. The key to keeping our relationship fresh and exciting is to learn something new about each other, every day.
Janet: Like what?
Sassan: Well like just now, what you learned about me is that I hate the key of B-flat major. That's something you didn't know about me until now.
Janet: Uh-huh.
Sassan: So? What am I going to learn about you today?
Janet: That I didn't know that you hated the key of B-flat major.

Well, that was helpful to know.
