Person 1: "Well, I'll see you at home later then. Should I phone when I'm leaving?"
Person 2: "No, I'll start cooking and you come home when you can."
A small hand-squeeze, a decorous kiss, a loving look and they parted ways, one for the Victoria/Piccadilly/Northern entrance, the other the Hammersmith & City/Circle/Metropolitan.
Now, this would have been a nice enough scene if it were to have contained a young, good-looking heterosexual couple. However. Person 1 was a podgy middle-aged man in a reflective jacket and paint-spattered overalls. Person 2 was a slightly taller, slightly older man wearing a suit and a smart overcoat and carrying a briefcase. ♥ ♥ ♥
