She was impressed, despite herself. You didn't often see proper dwarf halls these days. Most dwarfs were off earning big money in the cities down in the lowlands, where it was much easier to be a dwarf - for one thing, you didn't have to spend most of your time underground hitting your thumb with a hammer and worrying about fluctuations in the international metal markets. Lack of respect for tradition, that was the trouble these days. And take trolls. There were more trolls in Ankh-Morpork now than in the whole mountain range. Granny Weatherwax had nothing against trolls but she felt instinctively that if more trolls stopped wearing suits and walking upright, and went back to living under bridges and jumping out and eating people as nature intended, then the world would be a happier place.
