I go to the gym three times a week.  I spend much time watching people.  There are couples who work out together or, at least, come at the same time. There are a few that draw my attention.  I am aware that the men always walk in front or the women, even when not walking single file.  There is one man who comes from the weight room and walks over to the woman on the treadmill.  He nods, she gets off the treadmill, and they walk to the front door.  He hands her his bag.  He opens the front door and exits in front of her.  She follows, bag in hand.

I have remained quiet.
