One of the lines is: “The best cure for melancholy is industry.”
The movie is narrated by the wife in first person. She laments, “The wind carried off our speech, so we spoke less. And with work, I suppose, we had less to say.”
Another line: “I knew I would not be able to leave and I had to bite my cheek to keep from breaking into tears that, once started, could continue forever.”

Could it be “Silence of the North?”
