Step down

I'm standing at the head of the line at the Greenbelt Metro station R12 bus, because I'm on my way to a doctor's appointment. The disembarking bus opens its doors, a tiny white-haired lady bends down to lower her bag-on-wheels to the ground.  Two women, of varying ages and standing next to me, reach up and take the bag for her, then immediately reach back up to lend the lady a hand for that last, perilous step down. 

Such an elegant gesture.
