Parker felt suddenly reminded of the glass elevator from that book written by Roald Dahl about the chocolate factory, and vaguely he started to wonder whether they might start traveling side to side, or plunge down more stories than there were listed on the buttons. Almost instinctively he reached out and pressed the button for the first floor, but the elevator neither moved nor gave any indication of having even noticed that the button had been pushed again.
"Do you take the elevator because of your leg, then?" He nodded towards the cane, wondering how badly or inconvenient it must have been for this person who was so seemingly wary of a building to take an apparently sentient elevator.
