I see this scene every day. A man gets on the train with me and sits in two empty seats. He’s dressed to the nines. Full piece gabardine suit with a handkerchief peeking out of his pocket, silk tie to match, pale colored shirt, stylist shoes and artsy socks. I notice these things. His dark rimmed circle glasses makes him look like a scholar who belongs in a wing back chair in a well appointed library, smoking a pipe as he bends over his large book in his lap.
She gets on the next stop and smiles at him. He beams. She’s in a simple shirt, pants and running shoes. Her purse is a backpack. They huddle like lovebirds. He’s the talker, she’s the listener. Both wear wedding bands. Are they married to each other or is this a rendezvous? Perhaps they’re newlyweds. Both in their 50’s. They couldn’t be this besotted with each other otherwise.
Calvin says, “I vote for the rendezvous. That way you have entertainment for the ride home.” 
You need to sit closer so you can pick up some of the conversation! I vote newlyweds, because the alternative is too sad…
That would spoil my imagination!
