Celestia smiled at Tough Nut as he silently gave in. Clearly he hadn't actually put a lot of planning into her arrival here, judging by the way he thought overlooking the factory counted as a tour. Still, at least he had given in easy enough, but that sort of thing always left Celestia wondering if that was because she was good at out-manoeuvring ponies into these things, or if they were simply afraid to say no. Not a huge issue, but it still bothered her at times.
