With an almighty yelp, Ron released his hold on the rail and darted backward, thus ridding himself of the frightening ride up the set of sliding stairs. He slammed into an older woman that had been looking to ride the escalator up behind him, which immediately resulted in a series of unfavorable remarks from the woman. She thought he was being immature. Childish. The woman thought that he, Ronald Weasley, was another teenager playing around on devices that they ought not to.
Sort of true. But in his defense Ron didn't quite know what he was doing in the first place. Muttering a false apology, Ron pushed a hand through his ginger hair and turned to look off at the girl he'd heard speaking to him right before the collision with the older woman.
"Er, yeah," Ron said, lifting his shoulders and letting them drop in a sheepish sort of shrug. "I'm not...quite used to..." He gestured toward the escalator. "That. It's a bit frightening."
