The Apartment (1960)
Fran Kubelik: "We had two wonderful months this summer, but that was it. Happens all the time! The wife and kids go away to the country, and the boss has a fling with the secretary... or the manicurist... or the elevator girl. Comes September, the picnic is over; goodbye! The kids go back to school, the boss goes back to the wife, and the girl...... They don't make these shrimps like they used to."
