Travel Humor - A Very Long Trip

Location: Boston Logan Airport. 

I observed a "mature" couple walking along side by side, but farther apart than is usual for a couple.  Their unhappy faces caught my eye, and it was impossible not to overhear their "discussion":

Her: Yes, you are.
Him: No, I'm not.
Her: Yes, you are.
Him: (long pause) No, I'm not.
Her: (quickly) Yes, you are.

They were out of earshot at this point, but the back-and-forth appeared to continue.

Not sure where they were flying, but I do know it was going to be a very long trip.

Best comment - Sheryl Thomas Fowler: “Hopefully to a "grow up" conference?”
