It was a little bit hilarious to watch, but Sarah managed to keep a straight face as Molly slowly made her way down the perilous steps with only one hitch along the way (that had Sarah shooting forward like Molly was about to fall to her death).
She was probably just as relieved as Molly was when her friend was seated again. "Okay! Now! We walk!" She moved to assume the position behind the chair and edged it forward. "Where to, Madam? By the park?"
