A good parent never forgets:
To a 3 year old, there is nothing in the world more terrifying than an escalator.
To give you a visual, picture me boarding the escalator taking care to balance the baby stroller just right and my 3-year-old daughter standing at the top of the moving stairs, watching me drop into the depths of the marketplace with her liquid eyes, holding out her hand, screaming, "Daddy! Don't leave me!"
It's better to take the elevator.
