Quote from Moira in Love Letters
Moira: Well, well, "John-John" returns. Johnny: Okay, Moira, don't tell me you still haven't slept. Moira: What would give you that impression? Johnny: Sweetheart, you've got to find a way of getting some sleep! Moira: Easier said than done, John, when your only husband is longing for his epistle-writing inamorata.
