Zeek's at the end of his rope - the house is trashed, and there's no cereal or milk. He shaves and puts on a clean shirt, then skypes Millie in his boxers. She's extending her trip a week since they're both pursuing their passions. Defeated, Zeek drags himself to a local cafe for nourishment, but cafe-regular Rocky won't leave him in peace.

The next day, Zeek changes his tune, striking up a conversation with Rocky. It's an Army versus Navy battle, as the two rib each other and bond over growing old. However, Zeek goes on the defensive when Rocky assumes his wife is dead. Rocky's words of wisdom: Zeek should appreciate Camille - she isn't like most women their age, so he's lucky.
